LIVE Electrical RKB125C-030 25A 1P+N Type B RCBO C Curve 30mA 6kA Bi-Directional
Product Overview
The LIVE Electrical RKB125C-030 Type B RCBO is a compact, single-module residual current breaker with overcurrent protection, designed to provide reliable protection for modern electrical systems. It safeguards circuits against overloads, short circuits and earth leakage faults, while supporting advanced applications where DC residual currents may be present.
This Type B RCBO is engineered to detect AC, pulsating DC and smooth DC residual currents, making it suitable for installations where conventional protection devices may not offer adequate safety. Its bi-directional capability ensures secure operation in renewable energy systems and power electronics.
With a C-curve tripping characteristic, this RCBO is ideally suited to circuits with higher inrush currents such as EV chargers, solar PV inverters and heat pumps. Rated at 25A, with 30mA residual current sensitivity and a 6kA breaking capacity, it delivers dependable and compliant protection.
