Industrial Motor Starter

The Eaton AN19GN0A5E045 is a NEMA-rated magnetic motor starter designed for three-phase industrial applications. It provides non-reversing control for motors up to 45 A with electronic overload protection. This starter suits maintenance teams and panel builders who need reliable surface-mount motor control in a compact Freedom series enclosure.

Voltage and Overload Limits

The starter operates at a control voltage of 120V AC while the power circuit handles up to 600V AC. Its electronic overload relay adjusts between a minimum setting of 9 A and a maximum of 45 A. Selectable trip classes of 10, 20 and 30 allow coordination with different motor starting profiles, but the fixed 120V coil voltage cannot be changed for other control voltages.

45 A Current Rating Decides Fit

The single specification that determines suitability is the maximum overload relay current setting of 45 A. If the connected motor full-load current exceeds this value, the starter will not provide adequate protection. Buyers needing higher current capacity or reversing operation must select a different model, as this unit is strictly non-reversing and capped at 45 A.

Questions about this item

How do I decide between the 9 A minimum and 45 A maximum overload relay settings?

Choose a setting within the 9 A to 45 A range that matches your motor's full-load current; the electronic overload protection supports Trip Class 10A, 10, 20 and 30 for different acceleration profiles.

What does the 45 A overload rating mean once the starter is installed?

It defines the highest continuous current the electronic overload relay can be set to protect; the starter itself is a NEMA 3-pole, non-reversing contactor rated for 600 V AC maximum.

What voltage does the 120 V AC coil actually control?

The 120 V AC coil energises the contactor, which then switches three-phase power up to the 600 V AC rating of the power poles.
