Industrial motor starter for three-phase loads

The Eaton CN15GN3AB is a NEMA Size 2 non-reversing magnetic contactor rated for 45 A inductive current. It switches three-pole loads at 110/120 V AC coil voltage and mounts directly on a panel using screw terminals. The open-frame design carries a 15 hp rating at 240 V AC and 25 hp at 480 V AC three-phase.

Suited for panel builders wiring motor circuits

This contactor fits applications that need straightforward on/off control of three-phase motors up to the stated horsepower limits. The single 1NO auxiliary contact provides basic status feedback. Builders requiring reversing operation, additional auxiliary contacts, an enclosed housing or a different coil voltage should select another device.

Panel-mount frame with screw terminals for simple

The compact 5.05 in by 2.56 in footprint leaves space in crowded enclosures while the screw-terminal connections accept standard ring or fork lugs. The Freedom series frame ensures compatibility with Eaton accessories such as overload relays. No enclosure is included, so the installer must provide appropriate protection and clearances per local code.

Questions about this item

What control voltage must my control circuit supply to energise the coil?

The coil is rated for 110/120 V AC, so your control circuit must deliver that voltage to close the contactor.

Will the three main poles switch the 45 A motor load I already have on a 240 V three-phase supply?

Yes, the contactor is rated 45 A inductive and 15 hp at 240 V AC three-phase, matching that motor load.

How can I confirm the auxiliary contact has closed after the coil is powered?

With the coil energised, measure continuity across the single normally-open auxiliary terminals; a closed circuit shows the contactor has picked up.
