Product Description

The SIEMENS NEMA Magnetic Motor Starter: Reversing (SKU 22DUD32AA, MPN 22DUD32AA) is a three-phase reversing starter with electronic overload protection, NEMA Size 1, and a 27 A rating. It features a 110-120/220-240V AC dual-voltage coil, screw terminals, one normally open auxiliary contact, and a pilot light. No thermal units are required as the overload is electronic.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter: Reversing used for?

This reversing 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 provides electronic overload protection to safeguard the motor from overcurrent conditions, making it suitable for heavy-duty machinery in manufacturing and processing plants.

What are the specifications of the SIEMENS 22DUD32AA motor starter?

The SIEMENS 22DUD32AA is a NEMA Size 1 reversing starter rated for 27 A with three poles and electronic overload protection. It operates on a dual-voltage coil of 110-120/220-240V AC, includes one normally open auxiliary contact, screw terminals, and a pilot light. No thermal units are required.

Where to buy the SIEMENS 22DUD32AA motor starter worldwide?

You can source the SIEMENS 22DUD32AA reversing 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 supply genuine Siemens components for industrial motor control applications.

How to select the correct overload protection for a SIEMENS reversing starter?

For the SIEMENS 22DUD32AA, electronic overload protection is integrated, so no separate thermal units are needed. When selecting, match the starter's NEMA size and current rating (27 A) to your motor's full-load amps. Ensure the coil voltage matches your control circuit (110-120/220-240V AC) and that auxiliary contacts meet your interlocking requirements.
