The WKC350C 3 Pole 10kA MCB is a 50A C Curve miniature circuit breaker designed to protect three-phase circuits from overloads and short-circuits. With a 10kA breaking capacity and full compliance with BS 7671 (18th Edition), it’s a dependable choice for medium-to-heavy inductive loads including EV chargers, HVAC systems, motors, and solar PV installs. Bi-directional, compact, and DIN rail mountable, it ensures safe and flexible protection across commercial and industrial boards.

Installer Tip: Use C Curve MCBs when dealing with inductive circuits that draw moderate inrush currents. For resistive loads, check the B Curve model. For very high inrush circuits, select the D Curve.
