The WCED WARB5100C is a 5 Pole 100A Auto Resetting MCB designed for advanced three-phase systems where neutral and earth monitoring is required. It combines overload, short-circuit, and voltage monitoring with automatic reset after under-voltage events – reducing downtime on critical installations.
With integrated PME fault protection, the WARD5100C is trusted for EV charging boards, renewable systems with surge protection, and commercial three-phase distribution. Compact and compliant with BS 7671 (18th Edition), it’s built for residential, commercial, and industrial installs requiring maximum safety and reliability.
- 5 Pole, 100A rated – covers 3 phase + N + E protection
- Auto reset after under-voltage; manual reset after over-voltage
- PME fault protection – no earth rod required on TN-C-S supplies
- Overload & short-circuit protection – IEC/EN certified
- Complies with: BS EN 60898-1, BS EN 60947, BS EN 50557
- Dimensions: 107.2mm (W) × 82.4mm (H) × 78.5mm (D)
What’s the difference between the 3 Pole and 5 Pole auto-reset MCBs?
The 3 Pole WARD3100C is designed for three-phase loads only. The WARD5100C adds neutral and earth monitoring, making it fully PME fault-protected – ideal for EV and renewable installs.
Is this suitable for EV charging and solar systems?
Yes – it’s built for EV charger boards and solar/renewable installs where PME safety, voltage monitoring, and automatic reset functionality are required.
Does it reset automatically?
Yes. It automatically restores supply after under-voltage conditions. After an over-voltage trip, manual reset is required to comply with the 18th Edition Wiring Regulations.
Can this replace a standard MCB?
It can replace standard MCBs in compatible three-phase boards, but is recommended where continuous supply, PME protection, and voltage monitoring are essential.
What standards does it meet?
The WARD5100C complies with BS EN 60898-1, BS EN 60947, and BS EN 50557, ensuring full compliance for auto-reset devices in UK installations.
