How It Works
The WCED 4 Pole 63A 24V NC Modular Contactor operates using an electromagnetic coil:
- Default State: The contacts remain closed, allowing uninterrupted current flow in its normally closed (NC) configuration.
- Activation: When the 24V AC coil is energised, the magnetic field moves the armature, opening the contacts to interrupt the circuit.
- Fail-Safe Reset: Upon de-energising the coil, the spring mechanism resets the armature, returning the contacts to their closed position for reliable operation.
Applications
- Residential: Efficiently control high-capacity lighting, heating systems, and appliances.
- Commercial: Ideal for managing HVAC systems, retail lighting, and office equipment.
- Industrial: Suitable for heavy-duty applications such as motors, pumps, and large machinery.
