Eaton CN15KN3A 120 V AC 3-pole contactor

The Eaton CN15KN3A is a NEMA Size 3 non-reversing magnetic contactor rated for 90 A inductive load at 120 V AC coil voltage. It uses a three-pole configuration with screw terminals and a single normally open auxiliary contact. The unit is designed for panel mounting in industrial control panels and motor starter assemblies.

Suits motor control up to 50 hp at 480 V

This contactor suits applications switching three-phase motors up to 25 hp at 240 V AC or 50 hp at 480 V AC where a non-reversing starter is required. It does not suit installations needing a reversing starter, a built-in enclosure, or a coil voltage other than 110/120 V AC. Buyers who need higher current ratings, additional auxiliary contacts, or a different mounting style should look at other models.

No accessories or software bundled

The product ships as the contactor unit only with no additional accessories, wiring kits, or configuration software included. The transparent housing allows visual inspection of contact status without removing covers. Installers must supply their own mounting hardware, control wiring, and overload protection devices separately.

Questions about this item

What voltage control circuit do I need to operate the 120 V AC coil on this contactor?

The coil is rated for 110/120 V AC, so a standard 120 V AC control supply will energise it correctly.

Can I use this NEMA Size 3 contactor with a motor starter that was built for a smaller NEMA size?

No, the 4.08 in width and 7.17 in height require panel cut-outs and mounting holes that match the NEMA Size 3 footprint.

How can I confirm the three main poles are switching the 90 A load after installation?

Measure voltage across each pole with a multimeter while the coil is energised; you should read line voltage on the line side and near-zero voltage drop on the load side.
