A switch fuse with SPD can be useful where an installer needs fused isolation and surge protection before a dedicated board or downstream consumer unit
This unit is commonly used as a simple EV charger connection point where local isolation and circuit protection are required in one enclosure
Type A protection: Trips on AC and pulsating DC residual currents
It combines a 100A MCB main switch
Fire-resistant enclosure – Amendment 2 compliant
32A 4 Pole 10kA MCB B Curve – WKC432B Metal Surge Arrestor Unit A switch fuse with SPDThe 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
