FuseBox RTA063230B RCBO SPN 32A 30mA 6kA

The FuseBox RTA063230B is a 32A 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 circuits with low to moderate inrush currents such as socket outlets, lighting circuits, and general-purpose radial circuits. The Type A residual current protection detects both AC and pulsating DC fault currents, making it suitable for modern installations with electronic appliances and energy-efficient equipment.

With a 6kA short-circuit breaking capacity and 30mA earth leakage sensitivity, the RTA063230B provides reliable protection against electric shock and fire hazards. The device also includes double-pole switching (live and neutral isolation) for improved safety during maintenance and fault conditions.

Designed for use in FuseBox consumer units, it features a compact DIN rail-mounted single-module format with a flying neutral lead for quick installation. It complies with IEC/EN 61009-1 standards and supports current wiring regulations including the 18th Edition.
