The WKC432C is a 32A 4 pole 10kA Miniature Circuit Breaker (MCB) designed for three-phase + neutral systems. With a C Curve trip profile, it is suited to inductive load applications such as motors, pumps, HVAC units, EV charger circuits, and commercial lighting in distribution boards, EV installations, and solar PV setups.
Tested to a 10kA breaking capacity, the WKC432C ensures safe disconnection under overload and short-circuit conditions. It provides full neutral isolation, is bi-directional, DIN-rail mounted, and meets BS 7671 (18th Edition) standards.
Installer Tip: A 32A C Curve breaker is commonly used in commercial HVAC systems, medium-sized motor circuits, and EV charger boards. Always check the fault current does not exceed 10kA before installation.

What applications is the WKC432C suitable for?
It’s commonly used in HVAC systems, motor circuits, pumps, and EV distribution boards.
Why use a C Curve instead of a B Curve?
C Curve breakers tolerate higher inrush currents, making them suitable for inductive loads. B Curve breakers are for resistive loads only.
Can the WKC432C be used in EV charger setups?
Yes — the 32A C Curve is suitable for EV boards where moderate inrush is expected, provided the board fault current ≤10kA.
Does this product meet UK standards?
Yes, it complies with BS 7671 (18th Edition) and IEC/EN 60898-1.
