Choosing a Modular Contactor

A modular contactor allows a control signal to switch a separate load circuit. Choose it from the load type, utilisation duty, pole count, current rating and coil/control voltage—not from the headline amp rating alone.

2-Pole Contactors

Useful for switching suitable single-phase loads where the circuit design requires two switched conductors. Check the contact configuration and control circuit.

Browse 2-Pole Contactors →

4-Pole Contactors

Provide additional switched poles for suitable multi-pole or three-phase applications. Confirm whether the neutral is switched and how the load is distributed.

Control & Isolation

A contactor performs electrically controlled switching; it does not automatically replace the correctly rated protective device or local isolator.

Specification Checklist

Load type: identify resistive, inductive, motor, lighting or other duty
Current rating: use the appropriate utilisation category and manufacturer data
Pole configuration: confirm the number of conductors that must be switched
Coil voltage: match the control supply and switching equipment
Enclosure space: allow for DIN width, terminals, heat dissipation and wiring access
