The WKC450C is a 50A 4 pole 10kA Miniature Circuit Breaker (MCB) designed for three-phase + neutral protection. With its C Curve trip profile, it is best for inductive loads such as motors, pumps, HVAC systems, and EV charging boards in commercial distribution panels, EV setups, and solar PV installs.
Rated to 10kA breaking capacity, the WKC450C provides overload and short-circuit protection while isolating all live phases and the neutral. It is DIN-rail mounted, bi-directional, and manufactured in accordance with BS 7671 (18th Edition).
Installer Tip: The 50A C Curve breaker is suited for high-demand inductive circuits. Typical use cases include commercial HVAC compressors, pumps, and large EV distribution panels. Always confirm that fault current levels are ≤10kA.
