The WKC425C is a 25A 4 pole 10kA Miniature Circuit Breaker (MCB) designed to protect three-phase + neutral systems. With its C Curve trip profile, it is suitable for inductive loads such as motors, pumps, HVAC units, and EV charger circuits in commercial distribution boards, EV installations, and solar PV systems.
Rated to 10kA breaking capacity, the WKC425C provides reliable overload and short-circuit protection while isolating all three phases and neutral. It is DIN-rail mountable, bi-directional, and fully compliant with BS 7671 (18th Edition).
Installer Tip: The 25A C Curve breaker is a good fit for medium-sized inductive loads. Use for motor circuits, HVAC systems, or EV distribution boards with inrush current. Confirm fault levels ≤10kA.
