How It Works
The WCED 4 Pole 25A 4NC Modular Contactor operates using an electromagnetic coil activated by a 230V control voltage:
- Activation: Energising the coil creates a magnetic field that engages the armature, maintaining normally closed (NC) contacts in their default state.
- Switching: The robust NC contacts efficiently interrupt power flow when de-energized, offering reliable load control.
- Reset: A spring mechanism returns the armature to its default position when the coil is de-energized.
