Product Description

The SIEMENS NEMA Magnetic Motor Starter is a reversing starter with electronic overloads, featuring three poles, NEMA Size 0, and an 18 A rating. It operates with a 208V AC coil voltage and includes a pilot light for signaling, along with one normally open auxiliary contact. The unit uses screw terminals and requires no thermal units, as electronic overloads are integrated.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter used for?

This reversing starter controls three-phase motors up to 18 A, enabling forward and reverse operation. It is used in industrial applications such as conveyors, pumps, and hoists where direction change is needed. The integrated electronic overload protects the motor from overcurrent without requiring separate thermal units.

What are the specifications of the SIEMENS 22CUA32AD motor starter?

The SIEMENS 22CUA32AD is a NEMA Size 0 reversing starter with 3 poles, rated 18 A at 208V AC coil voltage. It includes a pilot light, one normally open auxiliary contact, and screw terminals. The electronic overload eliminates the need for thermal units. It is a three-phase device from SIEMENS.

Where to buy the SIEMENS 22CUA32AD motor starter worldwide?

3G Electric supplies the SIEMENS 22CUA32AD 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 genuine SIEMENS components for industrial applications.

How to install the SIEMENS reversing motor starter?

Mount the starter on a flat surface using the provided screw terminals. Connect three-phase power to the line side and the motor to the load side. Wire the 208V AC coil to the control circuit. The electronic overload is pre-set; adjust the dial to match motor full-load current. Follow SIEMENS wiring diagrams for reversing logic.
