The WKC306C 3 Pole 10kA MCB is a 6A C Curve breaker designed for protecting three-phase circuits against overload and short-circuit faults. Rated at 10kA breaking capacity and compliant with BS 7671 (18th Edition), it’s ideal for small inductive loads such as EV chargers, motors, and solar PV circuits. Compact, DIN rail mounted, and bi-directional, it provides reliable circuit protection in commercial and industrial installations.
Installer Tip: Choose the C Curve for inductive circuits where inrush currents are expected. For purely resistive loads, see the B Curve, or for very high inrush, the D Curve.
Key Features
- 6A rated current – suited for small three-phase inductive loads
- C Curve tripping – trips at 5–10x In for circuits with inrush
- 10kA breaking capacity – handles high fault levels safely
- 3 Pole design: complete three-phase protection
- Bi-directional: can be wired top or bottom
- Applications: motors, HVAC controls, EV/PV circuits
