FuseBox RTA062030B RCBO SPN 20A 30mA 6kA

The FuseBox RTA062030B is a 20A RCBO (Residual Current Breaker with Overcurrent Protection) designed to provide dual protection against overloads, short circuits, and earth leakage faults in residential and light commercial installations. It combines MCB and RCD functions in a compact single-module device, helping save space in consumer units while maintaining full circuit protection.

It has a B Curve tripping characteristic, making it suitable for general-purpose final circuits with low to moderate inrush currents such as socket outlets, lighting circuits, and small fixed loads. The Type A residual current protection allows it to detect both AC and pulsating DC leakage currents, making it suitable for modern installations with electronic appliances.

With a 6kA short-circuit breaking capacity and 30mA sensitivity, it provides protection against electric shock and fire risk by quickly disconnecting supply during fault conditions. The device also features 1P+N operation, meaning it connects to both live and neutral, with DIN rail mounting for installation in FuseBox consumer units.
