Lewden RCBO-B40/30/1PNAB Bi-Directional RCBO 40amp B Curve Type A 1P+N


The Lewden range of bi-directional RCBOs are designed for use with Lewden branded distribution boards, and are suitable for bi-directional power flow.

The switched neutral pole is particularly appropriate for systems featuring a TT earthing arrangement, or installations where it is necessary, for example EV charging.

In alternative power supplies such as Solar photovoltaic (PV), generators, and energy storage systems, the possibility of bi-directional power flow must be considered with respect to protective devices. Uni-directional RCBOs are not suitable for such applications.
