The WKC232B is a 32A 2 Pole 10kA Miniature Circuit Breaker (MCB) providing fast and reliable protection against short-circuit and overload faults. Designed for ring mains, small distribution boards, and fixed-appliance feeds, this B-curve breaker offers quick disconnection for resistive and low-inrush circuits.
Its dual-pole construction isolates both live conductors at once for enhanced safety and compliance with BS EN 60898-1. Compact 36 mm form factor fits any 35 mm DIN rail enclosure — ideal for domestic, light commercial, and EV-ready installs.
Installer Tip: A 32 A B-curve is commonly used on ring finals or single 32 A radial circuits supplying sockets or fixed equipment. For higher inrush devices such as compressors, choose the C-curve or D-curve variant.
Key Features
- 32 A rated – ideal for ring mains and small distribution feeds
- 10 kA breaking capacity – suited to commercial fault-level environments
- 2-pole isolation – disconnects both live conductors simultaneously
- B-curve tripping – fast acting for resistive or lightly inductive loads
- Bi-directional terminals – supply or load connection from either end
- Compact 36 mm (2-module) housing fits standard DIN rail
- Fully certified to IEC/EN 60898-1
- Compatible with consumer units and three-phase boards

Is a 32 A B-curve MCB suitable for ring mains?
Yes – it’s the standard rating for domestic or small-commercial ring final circuits under BS 7671.
Can this be used for a heat pump feed?
Yes – ideal for inverter-driven or low-inrush heat pump loads when a B-curve is specified.
Does it isolate both conductors?
Yes – the 2-pole design disconnects both live lines simultaneously for safe maintenance.
Is it 18th Edition compliant?
Fully compliant with BS EN 60898-1 and the 18th Edition Amendment 2 requirements.
