Frequently Asked Questions

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

A Siemens NEMA reversing magnetic motor starter, like the 22DUA32AH, controls the forward and reverse rotation of three-phase AC motors in industrial applications such as conveyors, hoists, and pumps. It includes an electronic overload relay for motor protection and a pilot light for status indication.

What are the specifications of the Siemens 22DUA32AH reversing starter?

The Siemens 22DUA32AH is a NEMA Size 1, three-pole reversing starter rated 27 A with a coil voltage of 380-440/440-480V AC. It features screw terminals, one normally open auxiliary contact, a pilot light, and an electronic overload that requires no thermal units.

Where to buy a Siemens 22DUA32AH reversing starter worldwide?

3G Electric supplies the Siemens 22DUA32AH reversing motor starter worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this NEMA Size 1, 27 A unit.

How to select a reversing motor starter for a three-phase motor?

Select a reversing starter by matching the motor's full-load current (FLC) and voltage to the starter's NEMA size and coil voltage. For a 27 A, 480V AC motor, the Siemens NEMA Size 1 starter (22DUA32AH) is appropriate. Ensure the electronic overload is set per motor nameplate data.
