Earth Leakage Sensors

Earth Leakage Sensors

Core balance earth leakage sensors with fixed and variable sensitivity to work in conjunction with circuit breakers and contactors to provide RCD protection. Devices are available with a wide range of sensitivities, suitable for current ratings from 1A to over 1000A, single or three phase.

MRCD series Variable Modular RCD and CTs

Loose MRCD sensors and CTs for purchase by OEMs for incorporation into their own assemblies or for use as spares within existing Blakley protection assemblies. The sensitivity adjustment range is 30mA to 30A dependent on the ID of the CT) and the time delay adjustment range is 0 to 10 seconds.
