Industrial motor starter for three-phase loads

The Eaton AN19DN0A5E005 is a NEMA-rated magnetic motor starter built for non-reversing three-phase applications. It mounts on a surface and uses an electronic overload relay that can be set between 1 and 5 amperes. The coil operates at 120 volts AC while the power contacts are rated up to 600 volts AC. One normally-open auxiliary contact is included for status signalling or interlocking.

Auxiliary contact and adjustable trip class

The single 1NO auxiliary contact changes state when the starter energises, giving a simple way to drive a pilot light or feed a PLC input without extra relays. Trip class can be selected from 10A, 10, 20 or 30 to match the motor’s acceleration profile, reducing nuisance trips on high-inertia loads. Electronic overload protection replaces traditional heater elements, so there are no parts to swap when the motor rating changes.

Limits of NEMA non-reversing design

The starter only runs the motor in one direction; applications needing forward and reverse must use a different device. Overload adjustment stops at 5 amperes, so motors drawing more current require a larger frame. The 120-volt AC coil voltage is fixed, so control circuits at other voltages need a separate transformer. Trip class selection is limited to the four preset values listed.

Questions about this item

Will the electronic overload relay on this NEMA starter need periodic recalibration or replacement after extended service?

The electronic overload relay is factory-calibrated and has no user-serviceable parts; it is designed to operate continuously within its 1 A to 5 A setting range without scheduled recalibration.

What is the first thermal or current limit reached when the starter runs at full 5 A load continuously?

The overload relay will trip according to the selected Trip Class 10A, 10, 20 or 30 curve once the sustained current exceeds the 5 A maximum setting.

How much heat does the starter dissipate and how loud is the contactor coil when energised at 120 V AC all day?

The coil draws standard NEMA holding power at 120 V AC and the contactor produces a low mechanical hum; surface mounting allows normal convection cooling without forced airflow.
