How It Works

The WCED 4 Pole 20A Modular Contactor uses an electromagnetic coil to manage electrical circuits:

1. Default State: In the normally open (NO) configuration, the contacts remain open, preventing current flow.
2. Activation: When the control voltage energises the coil, the magnetic field pulls the armature, closing the contacts to allow current flow.
3. Deactivation: Once the coil is de-energised, the contacts return to their open state, stopping the current flow.

Applications

• Residential: Ideal for controlling lighting systems, heating circuits, and automation devices.
• Commercial: Suitable for managing office lighting, HVAC systems, and small electrical loads.
• Light Industrial: Effective for controlling small motors, pumps, and other equipment.
