FuseBox RTA061630B RCBO SPN 16A 30mA 6kA

The FuseBox RTA061630B is a 16A 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 functions in a compact single-module device, helping to save space in consumer units while maintaining full circuit protection.

It features a B Curve tripping characteristic, making it suitable for general-purpose final circuits with low to moderate inrush currents such as lighting, socket radial circuits, and small fixed loads. The Type A residual current protection detects both AC and pulsating DC fault currents, ensuring compatibility with modern appliances and electronic equipment commonly found in today’s installations.

With a 6kA short-circuit breaking capacity and 30mA earth leakage sensitivity, the RTA061630B provides reliable protection against electric shock and fire risks. The device also includes double-pole switching (live and neutral isolation) for improved safety during maintenance and fault conditions.

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