Why Choose a 32A C Curve RCBO?
A C Curve RCBO is designed to tolerate higher short-duration inrush currents than a B Curve device. This can make it suitable for certain EV charger installations where the charger design or load characteristics may otherwise cause unwanted tripping.
The correct tripping curve should always be confirmed by the electrician. Earth fault loop impedance, cable size, voltage drop, installation method and protective device suitability should all be checked before installation.
