FuseBox RTA104030C RCBO 40A 30mA 10kA

he FuseBox RTA104030C is a high-performance 40A 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 installations. It integrates the functionality of an MCB and RCD into a single compact device, offering efficient, space-saving circuit protection.

Rated at 40A with a 30mA residual current sensitivity, the RTA104030C features a C-curve tripping characteristic, making it suitable for general-purpose circuits with moderate inrush currents such as lighting, sockets, and small appliances. It also provides a 10kA short-circuit breaking capacity, ensuring reliable interruption of high fault currents in demanding electrical environments.

The device is a 1P+N RCBO, meaning it switches the live conductor while also disconnecting the neutral for enhanced safety and isolation. 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, appliances, and IT equipment.
