The TOMZN TOB1L-63H 63A RCBO is a residual current circuit breaker with integrated overcurrent protection, designed to protect electrical circuits against overloads, short circuits, and earth leakage faults. By combining the functions of a miniature circuit breaker (MCB) and a residual current device (RCD) in one compact unit, it provides multiple layers of electrical protection while saving space in distribution boards.
Designed for 230V AC electrical systems, this 2-pole circuit breaker disconnects both live and neutral conductors when a fault occurs. Its 30mA residual-current sensitivity provides additional protection against electric shock, while the Type C tripping characteristic supports general electrical loads. The device mounts on a standard 35mm DIN rail and is suitable for compatible residential, commercial, and light industrial installations.
