This is the FuseBox RTA102030C 20A Type A C Curve RCBO – 30mA, 10kA Protection, available at SparksDirect.co.uk for the best price. The FuseBox RTA102030C is a 20A RCBO (Residual Current Breaker with Over-Current Protection) designed to provide comprehensive electrical protection in consumer units and distribution boards. By combining both miniature circuit breaker (MCB) and residual current device (RCD) functions in one compact unit, it safeguards individual circuits from overloads, short circuits, and earth leakage faults.
Featuring a 30mA residual current trip level and a 10kA breaking capacity, the RTA102030C helps reduce the risk of electric shocks and potential fire hazards caused by earth faults or overcurrents. Its Type A classification means it can detect both AC and pulsating DC leakage currents, making it suitable for modern electrical installations with diverse loads.
Compact and DIN-rail mountable, this RCBO is a versatile choice for residential, commercial, and light industrial applications where reliable circuit protection and compliance with wiring standards are essential.
Features and Benefits
- Combined Protection: Integrates overcurrent (MCB) and residual current (RCD) protection in a single device.
