The WKC463C is a 63A 4 pole 10kA Miniature Circuit Breaker (MCB) engineered for three-phase + neutral protection. With its C Curve trip characteristic, it is designed for heavier inductive loads such as motors, pumps, HVAC systems, EV charger circuits, and commercial sub-distribution boards in industrial and commercial systems, EV charging setups, and solar PV installs.

Tested to a 10kA breaking capacity, the WKC463C ensures dependable overload and short-circuit protection while providing full neutral disconnection. It is DIN-rail mounted, bi-directional, and fully compliant with BS 7671 (18th Edition).

Installer Tip: The 63A C Curve is the largest in the C Curve range. Use it for high-load inductive circuits where inrush currents are common — such as large HVAC compressors, industrial motors, and EV distribution panels. Confirm the installation fault level is ≤10kA.
