The WKC410C is a 10A 4 pole 10kA Miniature Circuit Breaker (MCB) designed for three-phase + neutral systems. With a C Curve trip characteristic, it is ideal for inductive load applications such as small motors, HVAC equipment, and EV charger sub-circuits in commercial three-phase boards, EV installations, and solar PV systems.
Rated to 10kA breaking capacity, the WKC410C provides reliable overload and short-circuit protection with full neutral disconnection. It is DIN-rail mounted, bi-directional, and compliant with BS 7671 (18th Edition).
Installer Tip: Select the 10A C Curve when protecting small inductive load circuits. Always check that the board’s fault level does not exceed 10kA before installation.

When should I use the WKC410C?
It is used for protecting small inductive load circuits such as motors, HVAC, and fluorescent lighting where moderate inrush current occurs.
How does a C Curve differ from a B Curve?
B Curve is for resistive loads with minimal inrush, while C Curve tolerates higher inrush, making it suitable for inductive circuits.
Is this MCB suitable for EV charger circuits?
Yes — the WKC410C is suited for EV sub-circuits that draw moderate inrush current, provided fault level is within 10kA.
Does this comply with BS 7671?
Yes, the WKC410C meets BS 7671 (18th Edition) and IEC/EN 60898-1 compliance.
