The WKC410B is a 10A 4 pole 10kA Miniature Circuit Breaker (MCB) designed for three-phase + neutral circuits. With a B Curve trip characteristic, it is suited for resistive loads such as lighting and socket circuits across three-phase distribution boards, EV installations, and solar PV systems.
Engineered with a 10kA breaking capacity, the WKC410B ensures overload and short-circuit protection while providing complete phase and neutral isolation. It is DIN-rail mountable, bi-directional, and compliant with BS 7671 (18th Edition).
Installer Tip: The 10A B Curve unit is ideal for small power or lighting sub-circuits. Use where inrush current is minimal and ensure board fault level does not exceed 10kA.
