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. Thermal units are not required as the overload is electronic.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter 22DUB32AH used for?

This reversing starter with electronic overload is used to control the direction of three-phase AC motors in industrial applications such as conveyors, hoists, and pumps. It provides forward/reverse operation and overload protection without requiring thermal units.

What are the specifications of the SIEMENS 22DUB32AH motor starter?

The SIEMENS 22DUB32AH is a NEMA Size 1 reversing starter rated 27 A with 3 poles. It has a 380-440/440-480V AC coil voltage, includes a pilot light and 1NO auxiliary contact, and uses screw terminals. The electronic overload eliminates the need for thermal units.
