How It Works

The WCED 4 Pole 40A 24V NC Modular Contactor functions using an electromagnetic coil:

  1. Default State: In its normally closed (NC) configuration, the contacts remain closed, allowing current to flow.
  2. Activation: Energising the 24V AC coil creates a magnetic field, moving the armature and opening the contacts to interrupt the circuit.
  3. Fail-Safe Design: When the coil is de-energised, a spring mechanism returns the contacts to their default closed position, ensuring safe and reliable operation.

Applications

  • Residential: Quietly manage lighting, heating systems, and appliances.
  • Commercial: Control office lighting, HVAC systems, and retail equipment.
  • Industrial: Efficiently handle motors, pumps, and machinery requiring reliable circuit control.

Why Choose This Contactor?

The WCED 4 Pole 40A 24V NC Modular Contactor is an excellent choice for professional electricians and engineers, offering durability, reliability, and silent operation. Its compliance with British standards ensures safe and efficient performance across various installations.
