The WAC4P100 is a robust 4 Pole 100 A modular contactor designed for EV charging hubs, solar systems, HVAC plant and heavy-duty automation circuits. It delivers reliable, noise-free switching across single- and three-phase loads, fitting standard 35 mm DIN rails inside modular enclosures and consumer units.
Engineered for demanding electrical environments, the WAC4P100 provides silent coil operation, high endurance, and compliance with BS EN 61095 and BS EN 60947-4-1. Suitable for both residential and commercial settings, it ensures safe, efficient control under the 18th Edition Wiring Regulations (BS 7671).
Installer Tip: Use the 100 A 4-pole model where multiple high-load circuits or three-phase plant require quiet, dependable switching. Always allow adequate spacing for heat dissipation within the enclosure and verify cable sizing for the full current rating.
- Silent coil – ideal for heavy-duty residential and industrial systems
- 4-pole configuration – supports three-phase control and neutral disconnection
- DIN-rail mountable for easy integration into boards and panels
- Compatible with AC-7a and AC-1 load categories
- Complies with BS EN 61095 and BS EN 60947-4-1
Available Variants (4 Pole Range):
