Product Description

The SIEMENS NEMA Magnetic Motor Starter is a reversing starter with electronic overloads, featuring 3 poles, NEMA Size 3-1/2, and a 115 A rating. It operates on three-phase power with a dual-range coil voltage of 110-120/220-240V AC. This unit includes a pilot light for signaling, one normally open auxiliary contact, and screw terminals for connection. No thermal units are required as it uses electronic overloads.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter used for?

This reversing starter controls three-phase motors up to 115 A, enabling forward and reverse operation. It is commonly used in industrial applications such as conveyors, hoists, and pumps where direction change is required. The electronic overload protects the motor from damage.

What are the specifications of the SIEMENS 22IUH32AA motor starter?

The SIEMENS 22IUH32AA is a NEMA Size 3-1/2 reversing starter rated at 115 A with 3 poles. It operates on three-phase power with a dual-range coil voltage of 110-120/220-240V AC. It includes a pilot light, one normally open auxiliary contact, and screw terminals. Electronic overloads eliminate the need for thermal units.
