FuseBox 45A 30mA Type B B Curve 6kA RCBO | RTB06B45BD

For individual circuit protection at 45A, the FuseBox RTB06B45BD RCBO pairs a B curve overcurrent characteristic with 30mA Type B earth leakage detection and 6kA breaking capacity.

Type B detects AC, pulsating DC and smooth DC residual currents, required where equipment can produce smooth DC fault currents such as some EV chargers, heat pumps and PV inverters. At 45A with a B curve characteristic it is typically used on electric showers and larger cooker circuits. Final device selection should always follow the circuit design, cable size, installation method and fault level of the installation.
