The WCED WKC Series 10kA MCBs are high-performance miniature circuit breakers designed for precise overcurrent detection and short-circuit protection. Built to handle demanding applications, they provide reliable protection for domestic, commercial, and industrial distribution systems – including solar PV and EV charging circuits.
Available from 6A to 63A in B, C, and D curves (D curve available on request), these MCBs are bi-directional and fully compliant with IEC/EN 60898-1 standards. Their compact single-pole design fits standard DIN rail slots and integrates seamlessly into WCED TP&N three-phase distribution boards.
- 10kA breaking capacity – robust protection against high fault currents
- Wide rating range – 6A to 63A
- Curve options: B, C, and D (D curve on request)
- Bi-directional – suitable for solar PV and EV applications
- Compliant with IEC/EN 60898-1
- Space-saving – single module width
What does 10kA breaking capacity mean?
It’s the maximum short-circuit current the breaker can safely interrupt without damage – 10,000 amps in this case.
Which curve type should I choose?
B curves are common in domestic installations, C curves for commercial or small industrial loads, and D curves for high inrush current equipment.
Are these MCBs suitable for solar or EV applications?
Yes – they are bi-directional and can be used in solar PV systems and EV charging circuits, provided they are rated appropriately.
Can I mix curve types in the same board?
Yes – as long as the curves and ratings are selected to suit the individual circuits and the installation design.
