How It Works
The WCED 4 Pole 40A Modular Contactor functions using an electromagnetic coil to control electrical circuits:
- Default State: In the normally open (NO) configuration, the contacts remain open, preventing current flow.
- Activation: When the coil is energised, the electromagnetic field pulls the armature, closing the contacts to allow current flow.
- Deactivation: Once the coil is de-energised, the contacts return to their default open state, halting current flow.
Applications
- Residential: Suitable for managing lighting, heating systems, and small household automation setups.
- Commercial: Ideal for office lighting, HVAC systems, and other medium electrical loads.
- Light Industrial: Effective for controlling motors, pumps, and small machinery.
