Eaton AN19GN0T5E045 NEMA Magnetic Motor Starter Non-Reversing 1NO 24V AC 3P

SKU CH-1DKR-4TVAN

NEMA magnetic motor starter with electronic overload protection adjustable from 9 to 45 amps and a 24 volt AC coil

  • TypeIndustrial Electrical Controls & Automation
  • Non-reversing starter simplifies motor control
  • Electronic overload protects from 9 A to 45 A
  • Selectable trip class 10A, 10, 20 or 30
  • 1NO auxiliary contact enables status signalling
  • Rated for 600 V AC three-phase operation

Product Purpose

The Eaton AN19GN0T5E045 is a NEMA magnetic motor starter designed for three-phase industrial applications. It provides non-reversing control with a 24V AC coil and includes one normally open auxiliary contact. This starter suits automation panels requiring electronic overload protection.

Upgrade Scope

The unit replaces older thermal overload starters by offering electronic protection with adjustable settings from 9 A to 45 A. The jump is worthwhile when Trip Class 10A, 10, 20 or 30 selectivity is needed for motor protection coordination. Surface mounting simplifies retrofit in existing enclosures.

Interface Limits

The starter is rated for a maximum of 600V AC across three poles. Operation is limited to non-reversing duty only. The 24V AC control voltage requires a compatible pilot circuit. Auxiliary signalling is restricted to a single 1NO contact.

Highlights

  • Non-reversing starter simplifies motor control
  • Electronic overload protects from 9 A to 45 A
  • Selectable trip class 10A, 10, 20 or 30
  • 1NO auxiliary contact enables status signalling
  • Rated for 600 V AC three-phase operation

Questions about this item

What surface-mount dimensions or clearance does the NEMA starter need for installation?

The starter uses a surface-mount style with three poles and a 600 V AC rating; allow enough panel space for the enclosure, wiring bends and the 1NO auxiliary contact block.

How do I wire the 24 V AC coil and the 1NO auxiliary contact, and what step is often missed?

Connect the 24 V AC control supply to the coil terminals and the 1NO auxiliary to the load circuit; the step often missed is setting the electronic overload between 9 A and 45 A and selecting the correct trip class (10A, 10, 20 or 30).

When should the electronic overload relay or the 1NO auxiliary contact be replaced?

Replace the overload relay if it trips repeatedly at the set current (9–45 A) or after a fault clears; replace the 1NO auxiliary contact if its switching becomes unreliable or contacts show wear.
