3-Pole 27 A Non-Reversing Contactor

The Eaton CN15DN3AB is a NEMA Size 1 magnetic contactor rated for 27 A inductive load. It switches three-phase motor circuits up to 7 1/2 hp at 240 V AC and 10 hp at 480 V AC. The 110/120 V AC coil suits standard control-voltage panels. Panel mounting with screw terminals simplifies installation in industrial control enclosures.

Upgrading from smaller NEMA sizes

The jump to NEMA Size 1 is worth it when the application demands 27 A full-load current or the listed three-phase horsepower ratings. It replaces Size 0 or fractional-hp contactors that cannot handle the same motor loads. The single 1NO auxiliary contact supports basic status feedback without extra accessories. Non-reversing design means it does not suit forward/reverse motor starters or applications needing direction change.

Panel-mount frame with screw terminals

The D-frame body measures 5.05 in high by 2.56 in wide and mounts directly on a panel. Screw terminals accept ring or fork lugs for secure power and control wiring. No enclosure is included, so the installer must provide a suitable cabinet or housing. The transparent colour allows visual inspection of contact status. One normally-open auxiliary contact is built in for pilot-light or PLC signalling.

Questions about this item

What panel cut-out and screw spacing does the 5.05 in by 2.56 in frame need?

The contactor measures 5.05 in high by 2.56 in wide and mounts on a panel with screw terminals; allow clearance for the overall height and width plus wiring space.

How do you wire the 110/120V AC coil and the three main poles, and what step is often missed?

Connect the coil to a 110/120V AC control circuit and the three power poles to the load using the screw terminals; the step often missed is tightening each screw terminal to the specified torque.

When should the auxiliary contact or the main contacts be replaced on a 27 A NEMA Size 1 unit?

Replace the 1NO auxiliary contact or the main power contacts when contact resistance rises, pitting appears, or the contactor fails to pull in cleanly at 27 A inductive load.
