LIVE Electrical RKB120C-030 20A 1P+N C Curve 6kA 30mA Type B Bi-Directional Compact RCBO
LIVE Electrical RKB120C-030 20A 1P+N Type B RCBO C Curve 30mA 6kA Bi-Directional
Product Overview
The LIVE Electrical RKB120C-030 Type B RCBO is a compact, single-module residual current breaker with overcurrent protection, designed to deliver reliable safety in modern electrical installations. It provides comprehensive protection against overload currents, short circuits and earth leakage faults, while supporting advanced applications that produce complex electrical waveforms.
This Type B RCBO is capable of detecting AC, pulsating DC and smooth DC residual currents, making it suitable for circuits where standard protection devices may not provide sufficient coverage. Its bi-directional power capability ensures safe operation in renewable energy and power conversion systems.
Featuring a C-curve tripping characteristic, this RCBO is ideal for circuits with higher inrush currents such as EV charging points, solar PV inverters, heat pumps and other inductive loads. Rated at 20A with a 30mA residual current sensitivity and a 6kA breaking capacity, it offers dependable and compliant circuit protection.
