FuseBox RTA102530C RCBO 25A 30mA 10kA

The FuseBox RTA102530C is a compact 25A Type A RCBO (Residual Current Breaker with Overcurrent protection) designed to provide combined protection against overloads, short circuits, and earth leakage faults in modern electrical distribution systems. It integrates the functions of an MCB and RCD into a single 1-module device, making it a space-saving solution for FuseBox consumer units.

Rated at 25A with a 30mA residual current sensitivity, the RTA102530C features a C-curve tripping characteristic, making it suitable for general-purpose circuits with moderate inrush currents such as socket outlets, lighting, and small appliances. It also offers a 10kA short-circuit breaking capacity, ensuring reliable fault interruption in residential, commercial, and light industrial installations.

The device is a 1P+N RCBO, meaning it switches the live conductor while also disconnecting the neutral for improved safety and isolation. Its Type A sensitivity enables detection of both AC and pulsating DC residual currents, making it suitable for modern electrical systems containing electronic loads such as LED lighting, IT equipment, and appliances.
