The WKC340C 3 Pole 10kA MCB is a 40A C Curve breaker built for protecting three-phase circuits with moderate inrush currents. Rated at 10kA breaking capacity, it provides safe disconnection during overload and short-circuit faults. Compact, bi-directional, and DIN rail mounted, it’s a reliable choice for EV charging points, solar PV distribution, HVAC systems, and industrial boards.
Installer Tip: Select a C Curve breaker when dealing with inductive circuits that generate moderate inrush currents. For lighting or socket loads, see the B Curve. For heavy inrush machinery, use the D Curve.
Key Features
- 40A rated current – protects larger three-phase inductive loads
