In most countries, the use of electrical devices is permitted if the manufacturer, upon his own responsibility, guarantees the conformity to the requirements. In other countries, the law lays down compulsory approval procedures. For better understanding of the subject, the information set out below deals with REQUIREMENT, CONFORMITY, APPROVAL. REQUIREMENTS This refers to the definitions contained in a standard relating to normal operating conditions, performance requirements, test procedures, etc. Requirements can be subdivided into: QUALITY MARK This is a special form of approval adopted for equipment for household use. The best known Authorities are: IMQ Istituto Marchio di Qualità, Italy KEMA-KEUR Keuring van Elektrotechnische Materialen, The Netherlands MARINE CLASSIFICATION This is a special form of approval adopted for equipment installed on board of ships. The best known Authorities are: RINA Registro Italiano Navale, Italy LROS Lloyd’s Register of Shipping, Great Britain BV Bureau Veritas, France Internationals requirements These are the requirements issued by the following Authorities: IEC International Electrotechnical Commission This international commission, with members from all the major industrialised countries, issues recommendations that are taken up as the basis of the single national standards. CENELEC Comité Européen de Normalisation Electrotechnique This committee issues the EN standards for the European countries. National Requirements For example, the requirements issued by the following Authorities: CEI Comitato Elettrotecnico Italiano, Italy VDE Verband Deutscher Elektrotechniker, Germany NF Normes Françaises, France CSA Canadian Standards Association, Canada UL Underwriter’s Laboratories, United States of America CONFORMITY Conformity to a standard consists of a declaration made by the manufacturer under his own responsibility to the effect that a specific product comply with all the requirements of the relevant standard. Recently, the CE Mark has been introduced, for which the manufacturer declares that the products comply with the EEC applicable Directives. For the electrical material the EEC applicable Directives are: LOW VOLTAGE Directive (72/23/EEC, modified to 93/68/EEC) for the safety of electric products and E.M.C. Directive (89/339/EEC, modified to 92/31/EEC and to 93/68/EEC) and Electromagnetic Compatibility. APPROVAL IIn some countries, approval of electric materials is compulsory by law. This consists of a certificate of conformity with the requirements issued not by the manufacturer, but by an independent Testing Laboratory legally recognized. Each approved item has to carry the mark of approval, such as CSA or UL. For this last, two different levels of acceptance are required: RECOGNIZED = The device should be marked with the letters UR only, and can be used in electrical equipment only by qualified personnel who are fully aware of the limits of use of the product. The sale of this equipment for general use is not permitted. LISTED = The device should be marked with the letters UL alongside the mark of approval and can be fitted in electrical appliances or sold loose, as it complies with all the requirements in the relevant standard. 27 TECHNICAL INFORMATION - DEFINITIONS Utilization category The standards define a certain number of categories with regard to the normal applications of contactors. Each category defines the current and the voltage values (expressed as multiples of the rated values) that corresponds to the connection and the switching of the load. Operating cycle A succession of operations from one position to another and back to the first position through all other positions, if any. Main circuit All the conductive parts of a switching device included in the circuit which it is designed to close or open Control circuit All the conductive parts (other than the main circuit) of a switching device which are included in a circuit used for the closing operation or opening operation, or both, of the device. Auxiliary circuit All the conductive parts of a switching device which are intended to be included in a circuit other than the main circuit and the control circuits of the device. Rated operational current Ie Current which takes into account the rated voltage, the rated frequency, the rated duty, the utilization category. Rated thermal current Ith The maximum current that a switching device can carry on eight-hour duty, without the temperature rise of its several parts exceeding the limits specified. Short-time withstand current The current that a switching device can withstand in the closed position during a specified short time, under prescribed conditions of use and behaviour. Time constant or Power factor The ratio between the inductance and resistance, that is L/R = mH/Ω=ms Clearance The distance between two conductive parts, along a string stretched the shortest way between these conductive parts Creepage distance The shortest distance along the surface of an insulating material between two conductive parts. Electrical durability It is defined as the number of on-load operating cycles which will be attained or exceeded by 90% of all devices tested without repair or replacement of any part. Mechanical durability It is defined as the number of no-load operating cycles which will be attained or exceeded by 90% of all devices tested without repair or replacement of any part. Pole impedance This is the complex resistance of a pole at rated current. Breaking or making capacity A value of prospective breaking or making current that a switching device is capable of breaking or making at the stated voltage under prescribed condition of use and behaviour. 28 Intermittent duty A duty with on-load periods, in which the main contacts of the equipment remain closed, having a definite relation to off-load periods, both periods being short to allow the equipment to reach thermal equilibrium. Intermittence ratio (I.R.) or operation factor (m) It represents the ratio between “t” duration of the current flow and “T” total operating cycle time, that is I.R. or m=t/T. Often this ratio is expressed as a percentage. For total operating cycle time, it is understood the time elapsing between the beginning of two consecutive passings of current. Opening time The interval of time between the specified instant of initiation of the opening operation and the instant when the arcing contacts have separated in all poles. Closing time The interval of time between the initiation of the closing operation and the instant when the contacts touch in all poles. Air ambient temperature It is the temperature, determined under prescribed conditions, of the air surrounding the complete switching device. For devices installed inside an enclosure, it is the temperature of the air outside the enclosure. Rated operational voltage Ue A value of voltage which, combined with a rated operational current, determines the application of the equipment and to which the elevant tests and the utilization categories are referred. Rated insulation voltage Ui The value of voltage to which dielectric tests and creepage distances are referred. TECHNICAL INFORMATION - UTILIZATION CATEGORIES Utilization with alternating current Utilization with direct current Power equipment , switchgear and controlgear according to EN 60947-4 and IEC 947-4 (contactors, equipment for starting of motors) Power equipment, switchgear and controlgear according to EN 60947-4 and IEC 947-4 (contactors, equipment for starting of motors) AC1 Connection or disconnection of non-inductive or slightly inductive loads (e.g. resistance furnaces). This equipment should have a cos no less than 0,95 DC1 AC2 Starting, counter-current braking and switching off of slip-ring motors. The contactor makes and breaks the starting current, which can reach 1,5 ÷ 3 times the rated current of the motor. DC3 AC3 Starting and switching off of squirrel-cage motors during running. The contactor makes the starting current, which can reach 4 ÷ 8 times the rated current of the motor, and breaks the rated current absorbed by the motor. The switching conditions are easy, as the voltage at the motor terminals is approximately 20 ÷ 30% of the supply voltage. Starting, plugging and inching of squirrel-cage motors. The contactor makes and breaks the starting current, which can reach 4 ÷ 88 times the rated current of the motor. The switching conditions are severe, as the voltage at the motor terminals can be equal to that of the supply voltage. Switching of electric discharge lamp controls. Switching of incandescent lamps. The peaks of current at the connection of the lighting circuits and the power factor are function of the type of lamp, the wiring system and the presence or not of the compensation. Switching of transformers. High peaks of current characterize the commutation of transformers during the connection phase, due to the phenomenon of magnetization. Switching of capacitor banks. High peaks of current characterize the commutation of capacitor banks during the connection phase, due to the presence of harmonic currents. AC4 AC5a AC5b AC6a AC6b DC5 DC6 Connection or disconnection of non-inductive or slightly inductive loads (e.g. resistance furnaces). This equipment should operate with a L/R time-constant less than or equal to 1ms. Starting, plugging and inching of shunt-motors. Dynamic breaking of DC motors. This equipment should operate with a L/R time-constant less than or equal to 2,5ms. The contactor makes and breaks the starting current, which is close to 2,5 times the rated current of the motor.

The current values indicated refer to those absorbed at full load by 3-phase squirrel-cage motors, 4 pole, 1500 rpm, 50 Hz, and by single-phase motors. These values are approximate, as they can slightly change according to the type of motor and the manufacturer. The thermal overload relay should therefore be adjusted for the current indicated on the motor nameplate and the rating of the fuse should be in proportion to this value,if different from that given in the table. 32 TECHNICAL INFORMATION - CO-ORDINATION WITH SHORT-CIRCUIT PROTECTIVE DEVICE When a disconnector, a contactor, a thermal overload relay, an automatic circuit breaker or a set of three fuses are chosen to realizes a plant, the problem of their mutual behaviour arises, that is to say their “co-ordination” on the basis of the electrical function carried out by each device. Symbol Device Function Notes Switch Control It makes, carries and switches the currents up to its making and breaking capacity. Being a device characterised usually by a limited breaking capacity, it is not able to switch high over-currents as those of short-circuit. Thermal overload relay Protection against overcurrent and phase failure It protects against thermal overloads included between 1,2 and times the rated current of the load (up to locked rotor condition, case of motors). This relay is characterised by a precise limit, represented by the max specific passing energy, beyond which an alteration of its tripping characteristic may occurs and, as an extreme case, the fusion of the heater elements. In fact, the thermal overload relay points out only the overload condition, delegating the real protection to the contactor, which switches the circuit. Fuses Protection against short-circuits They have not to trip in presence of a normal current overload. In order to avoid the fusion during the current peak which occurs motor starting, the fuse type gG will be chosen sized from 1,5 to 2,5 the full load current of the motor. Such fuse has therefore to carry for a relatively long time a current higher than the rated one and this may cause a thermal overload dangerous for the motor. In order to assure an effective protection of the motor, it is recommended to couple the thermal overload relay with fuses type aM (motor accompanying) whose current is of the same order of size than the current of themotor to be protected. Disconnector Disconnection This device allow to insulate, in a total and sure way, all the conductors placed on the load side, before carrying out any intervention on the plant, following a failure or a need of maintenance. Switch-disconnector Control Disconnection It groups all the above mentioned functions, relating to disconnector. Automatic circuit braker Control Protection against overloads Protection against short-circuits Direct-on-line starter Control Protection against overloads It groups more than one of the above mentioned functions. This equipment consists of a contactor coupled to a thermal overload relay, able of starting, stopping and protecting a motor. Notes The protective device (fuse or automatic circuit breaker) should be chosen in such a way to co-ordinate the starter for failure currents which exceed the breaking capacity of the contactor or the limit let through energy of the thermal overload relay. The device should be located on the supply side of the starter and have a short-circuit breaking capacity not less than the short-circuit prospective current at its location. “Fuse-combination unit” is a general term covering the combination of a switch, a disconnector or a switch-disconnector and one or more fuses in a composite unit. Such unit performs the different functions carried out by each electrical device composing the unit 33 PROGRESSIVE PART No. INDEX Part no. ord.
