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 190-220/220-240V 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 used for?

This reversing starter with electronic overloads controls three-phase motors up to 27 A, enabling forward/reverse operation in industrial machinery such as conveyors, hoists, and pumps. It is suitable for applications requiring NEMA Size 1 protection and pilot-light status indication.

What are the specifications of the SIEMENS 22DUB32AG motor starter?

The SIEMENS 22DUB32AG is a NEMA Size 1 reversing starter rated 27 A, 3 poles, with a 190-220/220-240V AC coil. It includes a pilot light, 1NO auxiliary contact, and screw terminals. The electronic overload eliminates the need for thermal units. It is a three-phase device.

Where to buy the SIEMENS 22DUB32AG motor starter worldwide?

3G Electric supplies the SIEMENS 22DUB32AG 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 and deliver this NEMA Size 1 starter to any country.

How to select the correct overload for the SIEMENS 22DUB32AG starter?

This starter uses an electronic overload, so no separate thermal units are required. Set the overload trip current according to the motor full-load amperage, following SIEMENS instructions. For motors up to 27 A, the built-in electronic overload provides adjustable protection without needing replacement heaters.
