IDMTL EARTH FAULT AND
OVERCURRENT RELAY
RSN200
Made In Japan
W• High Transient Withstand
E
N • EMC Compliant
• Fault Clearance Safety Reset
Kasuga Digital IDMTL Type RSN200 Earth Fault and Overcurrent Relay is designed to protect
electrical equipment and networks against overcurrent and ground fault. The relay comply to
BS 142 and IEC 255.
Some useful features of the relay :
• User friendly
• Compact in size
• Earth Fault can be configured to be
either IDMTL or DTL
• Earth Fault and Overcurrent setting is
selectable to either 1.3/10 or 3/10
curve
• Wider ranges setting in smaller steps
• Recall past % phase trip from memory store
in the relay
• Fully microprocessor controlled relay
• Built in surge arrester to absorb overvoltage/transient
• Mechanical trip reset button to guard against automatic
reset before fault is identified
• High set setting available
• Auto and manual scrolling of reading display selectable
