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.

Standard VELS series Variable Earth Leakage Sensors

Loose VELS sensors 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 100mA to 1A and the time delay adjustment range is 0 to 1 second. Devices are suitable for load currents of up to 125A, dependent on number, size and specification of the load conductors.
