The WKC420C is a 20A 4 pole 10kA Miniature Circuit Breaker (MCB) designed for three-phase + neutral systems. With its C Curve trip characteristic, it is suited to inductive load circuits such as motors, HVAC, pumps, and EV charging sub-circuits in commercial boards, EV distribution setups, and solar PV systems.
Offering a 10kA breaking capacity, the WKC420C ensures safe overload and short-circuit protection while isolating all live conductors and neutral. It is bi-directional, DIN-rail mounted, and compliant with BS 7671 (18th Edition).
Installer Tip: The 20A C Curve breaker is a versatile option for medium-duty inductive loads where inrush currents occur, such as fan motors, HVAC, and EV circuits. Confirm system fault level ≤10kA.
