The WKC432B is a 32A 4 pole 10kA Miniature Circuit Breaker (MCB) for three-phase + neutral protection. With its B Curve trip profile, this breaker is suited for resistive load circuits such as general socket banks, lighting, and small sub-distribution panels across commercial three-phase boards, EV charger setups, and solar PV systems.
Rated with a 10kA breaking capacity, the WKC432B ensures safe disconnection under overload or short-circuit conditions. It provides full neutral isolation, is DIN-rail mounted, bi-directional, and built to BS 7671 (18th Edition) standards.
Installer Tip: The 32A B Curve is a common choice for socket outlet circuits or distribution sub-boards with resistive loads. Confirm fault level does not exceed 10kA before use.
