Product Description

The SIEMENS NEMA Magnetic Motor Starter is a reversing starter with electronic overloads, designed for three-phase applications. It features a 208V AC coil voltage, NEMA Size 1 rating, 27 A capacity, and 3 poles. The unit includes a pilot light, 1NO auxiliary contact, and screw terminals for connection. Thermal units are not required as it uses electronic overloads.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter used for?

This reversing starter with electronic overloads controls three-phase motors in industrial applications such as conveyors, pumps, and hoists. It enables forward/reverse operation and protects against overloads. The 208V AC coil and NEMA Size 1 rating suit standard motor control panels.

What are the specifications of the SIEMENS 22DUA32AD motor starter?

The SIEMENS 22DUA32AD is a NEMA Size 1 reversing starter rated 27 A, 3 poles, with a 208V AC coil. It includes a pilot light, 1NO auxiliary contact, and screw terminals. Electronic overloads eliminate the need for thermal units. It is designed for three-phase applications.
