WCED Modular Contactors for Lighting, Heating & Control
Choose WCED DIN rail contactors for electrically controlled switching in lighting, heating and control panels. Start with the contact arrangement and coil supply, then match the current rating and utilisation category to the load.

Need manual isolation?
Browse rotary isolators when the job calls for manual circuit disconnection rather than coil-operated switching.

1
Contact arrangement
NO contacts are open with the coil de-energised; NC contacts are closed. Match the contact diagram to your control circuit.
2
Coil supply
Check the exact coil voltage and whether it requires AC or DC. This is separate from the voltage and current of the switched load.
3
Load and enclosure
Check the utilisation category, switching duty, dimensions, terminal capacity and ventilation requirements—not just the headline amp rating.
Planning an enclosure and components?
Our consumer-unit builder lets you choose single-phase or three-phase, select an enclosure and track the spare DIN space as you add supported components. Custom selections are supplied separately; factory-configured units have their own stated contents.

What does a modular contactor do?
A contactor uses an energised coil to operate electrical contacts, allowing a control circuit to switch a separate load circuit. It is not a replacement for circuit protection.
What do NO and NC mean?
Normally open and normally closed describe the contacts with the coil de-energised. NO contacts close when operated; NC contacts open.
Does CO always mean a transfer switch?
No. WCED CO-labelled variants may provide a combination of NO and NC contacts. Check the wiring diagram; do not assume the device is a complete source-changeover or interlocking arrangement.
Is a 63A contactor suitable for every 63A load?
Not automatically. The allowable current depends on load type and utilisation category, as well as the manufacturer's operating conditions. Motor and high-inrush loads need particular attention.
