Niglon 40 Amp Earth-Leakage Breaker RCD2-40/30

This Residual-Current Device (RCB) will quickly break an electrical circuit in your caravan to prevent harm from an ongoing electric shock. It works by comparing the current entering the appliance via the live wire with the current leaving the device through the neutral wire; the difference in the residual electric current - if it is too high, the device will interrupt the circuit.
