This WER40B-30 RCBO from WCED is ideal for electric vehicles, domestic and commercial applications.

Our RCBOs provide residual and overload protection in one neat device.

The WER Range RCBOs have switched neutral built in as standard, which will fully isolate a faulty or damaged circuit by disconnecting live and neutral conductors.

This RCBO has a twin handle system. The black handle controls the MCB function, and the white handle controls the RCD function.

If only the black handle trips, it indicates an overload or short circuit. If both white and black handles trip, it will indicate a residual current fault. This will assist the electrician to solve the fault quickly, saving time and money.
