The WAC4P125 is the most powerful model in our modular contactor range — a 4 Pole 125 A contactor built for reliable, noise-free switching of EV hubs, renewable energy systems, industrial lighting, and HVAC control panels. Designed for long service life, it delivers precise operation even under heavy, sustained loads.

This 4-pole unit provides complete phase and neutral isolation when required, fitting neatly on a 35 mm DIN rail inside modular enclosures and consumer units. It meets BS EN 61095 and BS EN 60947-4-1 standards for control and switching devices, ensuring full compliance with BS 7671 (18th Edition).

Installer Tip: Use the 125 A contactor where multiple three-phase or high-power single-phase loads are controlled under one distribution system. Always confirm cable size, protective coordination, and ventilation clearance within the board.

  • Silent coil design – suitable for industrial and commercial environments
