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 22DUD32AH reversing motor starter used for?

The SIEMENS 22DUD32AH is a NEMA Size 1 reversing magnetic motor starter rated 27 A at 480V AC. It controls three-phase motors that must change direction, such as conveyors, hoists, and pumps. The electronic overload protects the motor without requiring thermal units.

What are the specifications of the SIEMENS 22DUD32AH reversing starter?

This SIEMENS reversing starter is NEMA Size 1, 27 A, three-phase, 3-pole, with a 380-440/440-480V AC coil. It includes a pilot light, 1NO auxiliary contact, and screw terminals. The electronic overload eliminates the need for thermal units. MPN: 22DUD32AH.
