How It Works
The WCED 4 Pole 25A 24V NC Modular Contactor operates using an electromagnetic coil:
- Default State: In its normally closed (NC) configuration, the contacts remain closed, allowing current flow through the circuit.
- Activation: When the 24V AC coil is energised, the magnetic field moves the armature, opening the contacts and interrupting the current.
- Fail-Safe Reset: Upon de-energising the coil, a spring mechanism returns the contacts to their default closed state, ensuring reliable operation.
Applications
- Residential: Ideal for controlling lighting and heating systems.
- Commercial: Suitable for office lighting, HVAC systems, and retail applications.
- Industrial: Effective in managing motors, pumps, and machinery requiring fail-safe switching.
