Earth Fault Lockout Relays


The Dimako earth fault lockout system provides an intrinsically safe search voltage that interrogates system earth isolation, and will lock out circuit devices to prevent energisation onto an earth fault condition. The system is approved to latest SANS 60079-11 for intrinsic safety.

All devices are designed to operate continuously under sustained fault conditions. The unique design allows the system to be permanently connected to the circuit to be monitored (via a false neutral), with very little power dissipation. Led indication is given for trip and healthy conditions.
