1 / 1 page Protection Relays & Controls © 2015 Littelfuse Protection Relays & Controls SE-105, SE-107 SERIES Ground-Fault Ground-Check Monitor Description The SE-105/SE-107 is a combination ground-wire monitor and ground-fault relay for resistance-grounded systems. It continuously monitors the integrity of the ground conductor to protect portable equipment from hazardous voltages caused by ground faults. The SE-105/SE-107 is an excellent choice for trailing cables 5 kV and under in underground mining applications. For higher voltages or long-cable applications, see the SE-134C/SE-135.
