⚙️ Why Choose a 32A B Curve EV-Optimised RCBO?
The B Curve EV-Optimised RCBO included with this unit is ideal for EV chargers that draw steady loads without sudden spikes. With a trip threshold of 3–5x the rated current, it ensures quick fault response without nuisance tripping for standard installations.
Although B Curve breakers are generally used where inrush currents are low, always ensure your Zs values are within allowable limits. This should be verified by a qualified electrician following BS 7671 standards.
