Product Description

The SIEMENS NEMA Magnetic Motor Starter: Reversing (SKU 44N863, MPN 22DUC32AA) is a three-phase reversing starter with electronic overload protection, rated 27 A at NEMA Size 1. It features a dual-voltage coil (110-120/220-240V AC), screw terminals, one normally open auxiliary contact, and a built-in pilot light. No thermal units are required as the overload is electronic.

Frequently Asked Questions

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

A SIEMENS NEMA reversing magnetic motor starter controls the forward and reverse rotation of three-phase motors in industrial applications such as conveyors, hoists, and pumps. It combines electronic overload protection with a dual-voltage coil and pilot light for status indication.

What are the specifications of the SIEMENS 22DUC32AA reversing starter?

The SIEMENS 22DUC32AA is a NEMA Size 1, three-phase reversing starter rated 27 A with electronic overload protection. It has a dual-voltage coil (110-120/220-240V AC), screw terminals, one normally open auxiliary contact, and a built-in pilot light. No thermal units are required.
