How It Works
The WCED 4 Pole 20A Modular Contactor uses an electromagnetic coil to manage electrical circuits:
- Default State: In the normally open (NO) configuration, the contacts remain open, preventing current flow.
- Activation: When the control voltage energises the coil, the magnetic field pulls the armature, closing the contacts to allow current flow.
- 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.
