The WKC210B is a 10A 2 Pole 10kA Miniature Circuit Breaker (MCB) providing dependable protection for small power and lighting circuits. Its double-pole design safely disconnects both live conductors, helping installers meet isolation requirements under BS EN 60898-1 and the 18th Edition Wiring Regulations.
This 10A B-curve model is ideal for lighting circuits, immersion heaters, fans, and control panels where current inrush is minimal. The breaker’s compact 36mm body mounts on any standard 35mm DIN rail for quick installation.
Installer Tip: The 10A B-curve is often used for small single-phase sub-circuits or control feeds. For heavier inductive loads, use the C curve or D curve version.
Key Features
- 10A rated – suits lighting, control, or low-power socket circuits
- 10kA breaking capacity – suitable for higher fault-level environments
- 2-pole isolation – disconnects both live conductors simultaneously
- B-curve tripping – provides fast protection for resistive loads
- Bi-directional terminals – line or load connection from either end
- Compact 36mm width for standard DIN rail mounting
- Meets IEC/EN 60898-1 standards for circuit protection
- Compatible with consumer units, EV boards, and three-phase systems

| WKC210D | 10A | D Curve |
Can I use the 10A B curve for LED lighting?
Yes – 10A B curve MCBs are suitable for LED circuits with limited inrush current. For larger arrays or drivers with higher surge, use a C curve.
Does the breaker isolate both lines?
Yes – as a 2-pole MCB, it disconnects both live conductors at once, ensuring full isolation.
Is this compliant with the 18th Edition?
Yes, the WKC210B complies with BS EN 60898-1 and 18th Edition Amendment 2 requirements.
Is it suitable for EV sub-circuits?
Yes – often used in EV distribution boards to protect control or feed circuits rated up to 10A.
