The WKC206B is a 6A 2 Pole 10kA Miniature Circuit Breaker (MCB) designed to protect low-current lighting and socket circuits against overload and short-circuit faults. The double-pole configuration isolates both live conductors simultaneously, providing enhanced safety and compliance with BS EN 60898-1.
Built for precision and reliability, this B curve MCB delivers fast disconnection under low inrush conditions - ideal for domestic consumer units, garage boards, and small commercial installs. Compact 36mm body width fits any standard 35mm DIN rail.
Installer Tip: Select B-curve for lighting and resistive load circuits. For inductive or motor-heavy applications, step up to a C curve or D curve version.
Key Features
- 6A rated – ideal for lighting and small socket circuits
- 10kA breaking capacity – handles high fault levels in commercial installs
- 2 pole design – provides full isolation of both live conductors
- B-curve tripping – fast disconnection for resistive or low inrush loads
- Compact 36mm width – fits any standard DIN rail
- Compliant with BS EN 60898-1 – guaranteed regulation fit
- Bi-directional terminals – line or load connection from either end
- Suitable for EV-ready boards, three-phase systems and general sub-circuits

When should I use a B curve MCB?
B-curve MCBs are ideal for lighting, socket, and resistive load circuits where inrush current is low.
Does this MCB isolate both live conductors?
Yes – the 2-pole configuration ensures both conductors are disconnected simultaneously for maximum safety.
Is this suitable for EV or solar circuits?
Yes – it can be used in EV consumer units and solar applications, provided the circuit rating matches.
Is it compliant with UK wiring regulations?
Yes – manufactured to BS EN 60898-1 and fully compliant with the 18th Edition Wiring Regulations.
