Can I use this to replace a Siemens or Square D 4-pole contactor?

A: Yes, this is a universal replacement. As long as your original contactor is rated for 40 Amps (or less) and has a 24V Coil, this unit will work perfectly.

Can I use this to switch two separate heating elements?

Yes, absolutely. The 4-pole design functions as two separate 2-pole switches combined into one unit. This allows a single 24V thermostat signal to activate both heating circuits simultaneously, saving space and wiring complexity.

Does this contactor support Auxiliary Contacts?

Yes. This model features standard mounting points on the side for adding auxiliary contact blocks (Snap-on type), check our SUNLEE Auxiliary switch.

Can I use this contactor to control a bank of LED or ballast lights in a warehouse?

Yes, absolutely. You can use it to switch four separate 120V or 277V lighting circuits simultaneously using a single 24V low-voltage signal from a timer or photosensor.

My old contactor buzzes/hums — will replacing it fix that?

Often yes. Buzzing can be caused by a worn coil/armature, pitted contacts, or low control voltage. Replacing the contactor commonly resolves noise if the control voltage is stable and wiring is correct
