Product Description

The SIEMENS NEMA Magnetic Motor Starter is a reversing starter with electronic overloads, featuring three poles, NEMA Size 1, and a 27 A rating. It operates with a 380-440/440-480V AC coil voltage and includes a pilot light, 1NO auxiliary contact, and screw terminals. No thermal units are required as the overload protection is electronic.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter 22DUC32AH used for?

This reversing starter with electronic overloads controls three-phase motors up to 27 A, enabling forward/reverse operation in industrial machinery such as conveyors, hoists, and pumps. It is suitable for NEMA Size 1 applications requiring reliable motor protection and pilot-light signaling.

What are the specifications of the SIEMENS 22DUC32AH reversing starter?

The SIEMENS 22DUC32AH is a NEMA Size 1, three-pole reversing starter rated 27 A with a 380-440/440-480V AC coil voltage. It includes one normally-open auxiliary contact, screw terminals, a pilot light, and electronic overload protection. No thermal units are required.

Where to buy the SIEMENS 22DUC32AH reversing starter worldwide?

3G Electric supplies the SIEMENS 22DUC32AH reversing starter worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time; we source and deliver this Siemens-brand component to any country.

How to select the correct NEMA reversing starter for a motor?

Match the starter's NEMA size and current rating to the motor's full-load amps and voltage. For the SIEMENS 22DUC32AH, verify the motor is three-phase, 27 A or less, and the coil voltage matches your control circuit (380-440/440-480V AC). Electronic overloads eliminate the need for separate thermal units.
