FuseBox 20A 30mA Type B B Curve 6kA RCBO | RTB06B20BD

Combining an MCB and RCD in one unit, the FuseBox RTB06B20BD protects a 20A circuit against overload, short circuit and earth leakage, with 30mA Type B sensitivity and a 6kA rating.

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 20A with a B curve characteristic it is typically used on 20A radial socket circuits and dedicated appliance supplies. Final device selection should always follow the circuit design, cable size, installation method and fault level of the installation.
