FuseBox 40A 30mA Type A C Curve 10kA 3P+N Bi-Directional RCBO | R3PN10C4030BD

The FuseBox R3PN10C4030BD is a 40A 30mA Type A C curve RCBO with 10kA breaking capacity, combining overcurrent and residual current protection for one three phase circuit in a single device.

Type A detects AC and pulsating DC residual currents, the minimum type for most modern installations under BS 7671. Its bi-directional design allows supply to either set of terminals, so it can be used where current may flow in either direction, such as circuits fed by solar PV inverters or battery storage. As a 3P+N switched device it protects a complete three phase circuit, making it a fit for FuseBox TPN boards feeding motors, heaters, EV chargers and sub mains at 40A. Final device selection should always follow the circuit design, cable size, installation method and fault level of the installation.
