FuseBox RTA102030C RCBO 20A 30mA 10kA

The FuseBox RTA102030C is a compact 20A 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 device, delivering efficient, space-saving circuit protection.

Rated at 20A with a 30mA residual current sensitivity, the RTA102030C features a C-curve tripping characteristic, making it suitable for general-purpose circuits with moderate inrush currents such as lighting, socket outlets, and small appliance circuits. It also provides a 10kA short-circuit breaking capacity, ensuring reliable interruption under fault conditions 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 isolation and safety. Its Type A classification enables detection of both AC and pulsating DC residual currents, making it suitable for modern electronic loads such as LED lighting, IT equipment, and domestic appliances.

Designed for FuseBox consumer units and DIN rail mounting systems, the RTA102030C is compact (single module width), helping to maximise enclosure space while maintaining full protection per circuit. It complies with IEC/EN 61009-1 standards, ensuring conformity with current electrical safety requirements.
