The WKC416B is a 16A 4 pole 10kA Miniature Circuit Breaker (MCB) designed to protect three-phase + neutral circuits. With its B Curve trip profile, this breaker is suited for resistive load circuits such as general lighting, small appliance, and socket outlets in commercial boards, solar PV installs, and EV distribution setups.
Providing a 10kA short-circuit capacity, the WKC416B ensures safe disconnection under fault conditions. It delivers full 4-pole isolation (L1, L2, L3 + N), is bi-directional, DIN-rail mounted, and compliant with BS 7671 (18th Edition).
Installer Tip: The 16A B Curve MCB is commonly used on sub-circuits with moderate demand, such as small power and lighting loads. Always confirm that prospective fault current does not exceed 10kA.
Key Features
- 16A 4 Pole MCB – B Curve trip characteristic
- 10kA breaking capacity – reliable for commercial installs
- Neutral disconnection – 4P switching across all conductors
- Bi-directional feed – top or bottom cable entry
- DIN-rail mounted – 18mm per module
- Complies with BS 7671 (18th Edition)

| Model | Rating | Curve | Breaking Capacity |
|---|---|---|---|
| WKC410B | 10A | B Curve | 10kA |
| WKC416B (This Product) | 16A | B Curve | 10kA |

What type of loads is a 16A B Curve MCB used for?
It’s suited for resistive circuits like lighting and socket outlets where inrush current is minimal.
Why is a 4-pole breaker used instead of 3-pole?
It disconnects and protects the neutral conductor as well as all live phases, required in many three-phase + N systems.
Can I use the WKC416B in a solar PV install?
Yes, provided the connected load is resistive and fault level is within 10kA. For inductive or inrush-heavy circuits, use a C or D curve variant.
What approvals does this product meet?
The WKC416B is compliant with BS 7671 and IEC/EN 60898-1 standards.
