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.
Installer Tip: Use a 2-pole contactor like this for single-phase lighting banks or EV chargers where you need to isolate both live conductors at once – a common requirement under BS 7671 for domestic and EV applications.
- 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
Available Variants (2 Pole Range):

What is the purpose of a 2 Pole Modular Contactor?
It switches and controls single-phase circuits such as lighting, heating, EV chargers and automation loads — providing safe, reliable, and silent operation.
Is the WAC2P20 suitable for residential installs?
Yes – its quiet coil design and compact DIN footprint make it ideal for residential and commercial applications.
Can it be used with EV and renewable circuits?
Yes – it pairs well with EV charger boards and heat pump systems. For full compliance, use alongside surge protection devices.
Does it make noise when switching?
No – the WAC2P20 is designed for silent operation, suitable for indoor living and office environments.
Is it compliant with UK regulations?
Yes – it conforms to BS EN 61095 and BS EN 60947-4-1, meeting the requirements of the 18th Edition Wiring Regulations (BS 7671).
