How It Works

The WCED 4 Pole 125A Modular Contactor operates via an electromagnetic coil to manage electrical circuits:

1. Default State: In its 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 and allowing current flow.
3. 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.
