Product Description

The SIEMENS NEMA Magnetic Motor Starter: Reversing (MPN 22DUC32AD) is a three-phase reversing starter with electronic overloads, NEMA Size 1, rated 27 A. It features a 208V AC coil voltage, screw terminals, one normally open auxiliary contact, and a pilot light signaling feature. Thermal units are not required as the overload protection is electronic.

Frequently Asked Questions

What is the SIEMENS 22DUC32AD reversing motor starter used for?

The SIEMENS 22DUC32AD reversing motor starter is used to control the forward and reverse rotation of three-phase AC motors in industrial applications such as conveyors, hoists, and pumps. It integrates electronic overload protection and a pilot light for status indication, making it suitable for automated machinery requiring directional control.

What are the specifications of the SIEMENS 22DUC32AD motor starter?

The SIEMENS 22DUC32AD is a NEMA Size 1 reversing starter rated 27 A with a 208V AC coil voltage. It has three poles, screw terminals, one normally open auxiliary contact, and an electronic overload that eliminates the need for thermal units. It includes a pilot light for signaling and is designed for three-phase systems.

Where to buy the SIEMENS 22DUC32AD motor starter worldwide?

You can source the SIEMENS 22DUC32AD reversing motor starter through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide competitive pricing and reliable sourcing for this Siemens component.

How to select the correct overload protection for the SIEMENS 22DUC32AD starter?

The SIEMENS 22DUC32AD uses an electronic overload relay, so no separate thermal units are required. When selecting, ensure the motor full-load current does not exceed the starter's 27 A rating and that the coil voltage matches your control circuit (208V AC). Always consult the motor nameplate and Siemens documentation for proper coordination.
