The WKC416B is a 16A 4 pole 10kA Miniature Circuit Breaker (MCB) designed to protect three-phase + neutral circuits. With its B Curve trip profile, this breaker is suited for resistive load circuits such as general lighting, small appliance, and socket outlets in commercial boards, solar PV installs, and EV distribution setups.
Providing a 10kA short-circuit capacity, the WKC416B ensures safe disconnection under fault conditions. It delivers full 4-pole isolation (L1, L2, L3 + N), is bi-directional, DIN-rail mounted, and compliant with BS 7671 (18th Edition).
Installer Tip: The 16A B Curve MCB is commonly used on sub-circuits with moderate demand, such as small power and lighting loads. Always confirm that prospective fault current does not exceed 10kA.
