RCBO - Residual Current Breakers

RCBOs from Hager, Eaton, Chint and Garo. Single-pole, 1P+N, 2-pole and 4-pole RCBOs in B and C curves, rated from 6A to 50A, mostly 30mA Type A with some 100mA options, and bi-directional RCBOs, which Hager describes as suited to solar PV, battery storage and EV charging circuits. An RCBO gives overcurrent and earth leakage protection on one circuit, so a fault only trips that circuit.
