● Essential difference between the basic characteristic curve of the
SMPS and the TPS characteristic in the overload range:
- TPS: high overload capability, as power P = U x I ~ constant
- SMPS: overload behaviour depends on manufacturer, type,
current rating of the SMPS (10 A/20 A/30 A/40 A), often the
output voltage will be regulated (self-protection of the SMPS) or
shut down commencing already at 1.1…1.5 times rated current.

Questions arising
in the planning stage
1. Power supply
● Type, manufacturer, current rating, output characteristics,
overload behaviour, price...)?
● Utilisation ratio of the power supply during dynamic
operation of the equipment?
● Current reserve for a later expansion of the system
(up to 80 % utilisation)?
2. Load characteristics
● What loads shall be protected?
● What is the dynamic characteristic of the load current during
start up or on duty in a group protection?
3. Protection
● Selection of current rating and trip curve of the circuit breaker:
fast or medium delay?
● What is the total current consumption with protection of
groups of devices?
● Is selectivity ensured in the event of short circuit or overload?
● How do connected devices respond to voltage dips?
4. Wiring
● What will be the cable lengths?
● What is the cable cross section of the individual harness (sensor
cables 0,25 mm2, wiring 1 / 1,5 / 2,5 mm2, mixed forms, I2t value)?
● Can the device trip due to cable attenuation ?
● Wiring time and work for load lines (plus, protected load output,
minus, functional earth) and signal contacts in the control
cabinet?
Power supply
1. Power supply DC 24 V
● DC 24 V control voltage: Switch-mode power supplies (SMPS)
today widely replace the traditional transformer power supplies
(TPS). Reason: Size, weight, efficiency ...

Load characteristics
2. Load characteristics (during start up, dynamic processes
on duty)
● Electronic system components (sensors, PLC, user terminals,
drive controls, field BUS modules etc.) have a high input capacity
= high inrush current. Reason: a multitude of EMC and buffer
capacitors, number will further rise because EMC standards are
revised for voltage dips in DC systems
● DC 24 V motors for small drives and fans have high start-up
currents
Protection
(conventional)
MCB (branch protector)
with C-characteristic
3. Protection: rated current, trip curve, selectivity at DC 24 V
● Thermal-magnetic circuit breakers
- Fast DC trip curves (F1, A, Z or B in the lower tolerance
band): Magnetic short circuit trip at 3...5 x IN
or 4.5...7.5 x IN of the circuit breaker.
- Medium delay DC trip curves (M1, C): trip at 7.5...15 x IN
Thermal-magnetic type, C-characteristic / DC
trips magnetically between 7.5 and 15 times rated
current
Example: IN = 6 A:
The required trip current is between 45 A and 90 A
PROBLEM 1
→ Fast trip curve:
Electronic system components often cannot be switched on,
as a high inrush current trips the breaker.
PROBLEM 2
→ Medium delay trip curve:
SMPS cannot supply current necessary to trip the breaker,
the output voltage has been turned down or shut down.
e. g. a breaker with IN = 4 A needs a trip current of 30...60 A !
RESULT:
→
→
→
Failure of all circuits
System stoppage
Trouble-shooting is time-consuming
MCB according to
IEC / EN 60898

The power supply cannot provide this trip current and shuts down

When using electronic circuit breakers for protection, the cable
will be protected because of the electronic current limitation and
the fast overcurrent disconnection – even at a current rating of
3 A and a cable cross section of 0.25 mm2!

max. permissible distance at 1.5 mm2 and 6 A
106 m (100 m is equivalent to 2.37 Ohm), 106 m is equivalent to 2.37 Ohm)
mixed wiring:
R1 = 40 m in 1,5 mm2 and R2 = 5 m in 0.25 mm2:
(control cabinet --- sensor-/actuator level)
R1 = 0.95 Ohm R2 = 0.71 Ohm
total (R1 + R2) = 1.66 Ohm
Different cable lengths and cross section
Empirical formula (*1): ESS20/ESX10 rated 3 A can protect
output resistance up to 5 Ω!
Empirical formula (*2): for ø 1.5 mm2:
50 m distance = 100 m cable length
= 1.2 Ω cable attenuation!
I2t-value/current capacity
of a 0.14 mm2 cable
Example 4:
Cable 2 x 0.14 mm2,
length 10 m
material Cu, PVC insulation,
max. Joulean effect according to data sheet:
I2t = 260 A2s
Protection by means of ESS20, ESX10 , ESX10-T at = 3 A:
● overload disconnection at max. 3.75 A within 5 sec:
I2t = 80 A2s (< 260 A2s)
● short circuit disconnection at max. 6 A within 100 ms:
I2t = 3,6 A2s (<< 260 A2s)
● within 1 sec:
I2t = 36 A2s (<< 260 A2s)
12
Addendum to 4.: Wiring and Ampacity
● Example:
10 m sensor cable, cross section 0.14 mm2
● Result:
The I²t values of the ESS20 and similar models at overloads of
2 x IN plus or short circuit are far below the max. I²t value of the
0.14 mm2 cable.
The “I2t - limiters”:
ESS20, ESX10 and ESX10-T provide cable protection due to
electronic current limitation and fast overcurrent disconnection,
even at 3 A rated current and 0.25 mm2 !
0.14 mm2 has a max. cont. load of only 2 A at 30 °C.
In comparison (C curve see page 5):
● Short circuit disconnection of C3 MCB: disconnection at 4 x IN
after 3 s...max. 15 sec
I2t = (12 x 12) A2 x t = 144 A2 x 15 s = 2160 A2 s (>> 260 A2s)
The cable will be destroyed!

● Economic and space-saving cabinet design
● Saving up to 50 % of the costs by using cascadable power
distribution systems for DC 24 V accommodating electronic
circuit breakers
● Additional benefits through additional electronic
sub-assemblies:
- intelligent alarm processing
- remote control
- bus connection
- emergency functions
Comparison
of control cabinet concepts
● In machinery and industrial plants:
switch-mode power supplies generate the DC 24 V
control voltage (output current 5 A…40 A)
● Protection:
MCBs versus electronic circuit breakers
● Flexibility and cost-effectiveness of power distribution
and wiring
● Possible integration in centralised and decentralised
solutions
