EV & Heat Pump Compatible Units
Many of our consumer units are engineered for modern inverter-driven equipment such as electric vehicle chargers and heat pumps. These units provide the correct RCD/RCBO pairing and allow straightforward integration of surge protection and PME fault-disconnection solutions.
