Product Description

The SIEMENS NEMA Magnetic Motor Starter: Reversing (SKU 44N869, MPN 22DUD32AF) is a three-phase reversing starter with electronic overloads, featuring a 110/120V AC coil voltage and NEMA Size 1 rating at 27 A. It includes a pilot light, one normally open auxiliary contact, and screw terminals. Thermal units are not required as the overload protection is electronic.

Frequently Asked Questions

What is a Siemens NEMA reversing magnetic motor starter used for?

A Siemens NEMA reversing magnetic motor starter, like the 22DUD32AF, controls the forward and reverse rotation of three-phase motors in industrial applications such as conveyors, hoists, and pumps. It includes electronic overload protection and a pilot light for status indication.

What are the specifications of the Siemens 22DUD32AF reversing starter?

The Siemens 22DUD32AF is a NEMA Size 1 reversing starter rated 27 A, 3 poles, with a 110/120V AC coil. It includes one normally open auxiliary contact, screw terminals, a pilot light, and electronic overloads that eliminate the need for thermal units.
