The WKC320C 3 Pole 10kA MCB is a 20A C Curve breaker built to safeguard three-phase circuits against overload and short-circuit faults. With a 10kA breaking capacity and full compliance with BS 7671 (18th Edition), it’s ideal for circuits with moderate inrush currents such as EV chargers, motors, and solar PV systems. Compact, DIN rail mounted, and bi-directional, it delivers reliable protection in commercial and industrial environments.

Installer Tip: Choose C Curve breakers for inductive circuits like motors, HVAC, or EV chargers. For resistive loads, see the B Curve. For heavy inrush loads, use the D Curve model.
