How Contactors Work

Contactors function as electrically controlled switches that enable or interrupt the flow of electrical power. The WCED Modular Contactor uses a 24V DC electromagnetic coil, energized by a 230V AC control circuit, to perform its switching operations:

1. Electromagnetic Coil Activation:
   • When the 230V AC control circuit energizes the coil, it creates a magnetic field.
   • This field pulls the armature, closing the normally open (NO) contacts and allowing current to flow to the connected load.
2. Load Switching:
   • The contacts are made of high-quality materials, such as silver alloys, to withstand high currents and minimize arcing.
   • The modular design allows for efficient load switching in applications like lighting, heating, and motor control.
3. Reset Mechanism:
   • When the control circuit is de-energized, the spring mechanism returns the armature to its original position, reopening the contacts and stopping the flow of power.

Applications:

• Residential: Lighting, heating systems, and garden pumps.
• Commercial: HVAC systems, ventilation, and large-scale lighting setups.
• Industrial: Motor control, conveyors, and automation systems requiring repetitive switching.
