2 Pole Modular Contactor – 20 A

The WAC2P20 is a compact 2 Pole 20 A modular contactor built for reliable, silent switching in residential, commercial, and light-industrial circuits. Designed for lighting control, HVAC, EV chargers, and automation systems, it integrates cleanly into modular enclosures and consumer units.

It provides quiet operation, a long mechanical life, and a compact footprint that fits standard 35 mm DIN rails - making it ideal for installations where noise and space must be minimised. Fully compliant with BS EN 61095 and BS EN 60947-4-1, the WAC2P20 ensures safe switching for AC loads up to 20 A.

• Silent operation – suitable for residential and commercial use
• DIN-rail mountable within modular boards and enclosures
• Compact design with clear terminal markings
• Rated for AC-7a (resistive) and AC-1 (inductive) loads
• Complies with BS EN 61095 and BS EN 60947-4-1
