4 pole 10kA MCB's 10A B Curve WKC410B Metal Surge Arrestor Unit Bi-directional wiring – suitable forThe 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
