FuseBox RTA060630B RCBO SPN 6A 30mA 6kA

The FuseBox RTA060630B is a 6A RCBO (Residual Current Breaker with Overcurrent Protection) designed to provide combined protection against overloads, short circuits, and earth leakage faults in residential and light commercial electrical installations. It integrates MCB and RCD functionality into a compact single-module device, helping save space in consumer units while maintaining full circuit protection.

It features a B Curve tripping characteristic, making it suitable for low inrush current circuits such as lighting, smoke alarms, control circuits, extractor fans, and other small fixed loads. The Type A residual current protection detects both AC and pulsating DC fault currents, making it compatible with modern electrical installations that include electronic devices and energy-efficient appliances.

With a 6kA short-circuit breaking capacity and 30mA earth leakage sensitivity, the RTA060630B provides reliable protection against electric shock and fire hazards. It also includes double-pole switching (live and neutral isolation) for improved safety during maintenance and fault conditions.

Designed for FuseBox consumer units, it is a compact DIN rail-mounted single-module device with a flying neutral lead for straightforward installation. It complies with IEC/EN 61009-1 standards and supports 18th Edition wiring regulation requirements.
