RCBO is a residual current operated circuit breaker, mainly used to protect the circuit and personnel safety. It detects any current leakage in the circuit beyond the rated sensitivity and automatically disconnects the circuit in the event of a fault. RCBO is widely used in residences, commercial buildings, industrial fields, medical fields, laboratories, and scientific research fields where circuits and equipment need to be protected from leakage currents. Compared with RCD, RCBO is a comprehensive protector that can not only realize leakage protection, but also realize overload and short circuit protection, which is safer and more reliable.
ETEK Electric provides various types of RCBO (AC, A, S, B, EV (A+DC6mA)) to meet different application scenarios.
