The WKC463B is a 63A 4 pole 10kA Miniature Circuit Breaker (MCB) designed for three-phase + neutral protection. With its B Curve trip characteristic, it is best suited to resistive load applications such as large socket outlet groups, small power distribution panels, and lighting circuits in commercial three-phase systems, EV distribution boards, and solar PV setups.
Offering a 10kA breaking capacity, the WKC463B provides dependable overload and short-circuit protection with full 4-pole disconnection. It is bi-directional, DIN-rail mounted, and built to BS 7671 (18th Edition) compliance.
Installer Tip: The 63A B Curve is the largest unit in this series. Ideal for high-load resistive circuits in commercial environments. Always confirm the installation fault current is within 10kA before use.
