How It Works
The WCED 4 Pole 125A Modular Contactor operates via an electromagnetic coil to manage electrical circuits:
- Default State: In its 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 and allowing current flow.
- Deactivation: When the coil is de-energised, the contacts return to their open state, halting current flow.
Applications
- Residential: Suitable for managing high-capacity heating systems or large lighting loads.
- Commercial: Ideal for HVAC systems, retail lighting, and office equipment control.
- Industrial: Designed for heavy-duty machinery, motors, and pumps.
