100A 2 Pole 100mA Time Delay RCD


An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire.

It can also provide some protection against electrical fires. RCDs offer a level of personal protection that ordinary fuses and circuit-breakers cannot provide.

The Cudis Time Delayed RCD’s are sensitive safety devices that switch off electricity automatically if there is a fault.

An RCD is designed to protect against the risks of electrocution and fire caused by earth faults.  For example, if you cut through the cable when mowing the lawn and accidentally touched the exposed live wires or a faulty appliance overheats causing electric current to flow to earth.

The Cudis range of RCDs are available in 25A, 40A, 63A, 80A & 100A versions. They feature an integral test button and come with our renowned 5 year warranty.
