Description Reviews FAQSs Technical Specs Installation Notes

The WKC310C 3 Pole 10kA MCB is a 10A C Curve breaker designed to protect three-phase circuits from short-circuit and overload faults. Rated at 10kA breaking capacity and BS 7671 (18th Edition) compliant, it’s widely used in industrial boards, EV chargers, and solar PV installs. Its C Curve tripping profile allows safe operation on circuits with higher inrush currents such as motors and HVAC systems.

Installer Tip: Choose C Curve breakers for inductive circuits with inrush (motors, HVAC, EV chargers). For resistive loads, see the B Curve. For heavy inrush, check the D Curve.

Key Features

10A rated current – protects small three-phase inductive circuits
C Curve tripping – operates at 5–10x In
10kA breaking capacity – ensures safe disconnection under fault
3 Pole design: covers three-phase systems
Bi-directional: wiring possible from top or bottom
Applications: motors, HVAC, EV chargers, PV boards
