Product Description

The SIEMENS NEMA Magnetic Motor Starter is a non-reversing starter with an electronic overload, designed for three-phase applications. This NEMA Size 1 unit (MPN 14DUB32AF) features a 110/120V AC coil, 27 A rating, screw terminals, a pilot light, and one normally open auxiliary contact. Thermal units are not required as the overload protection is electronic.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter used for?

The SIEMENS NEMA Magnetic Motor Starter is used to start and stop three-phase motors in industrial applications such as conveyors, pumps, and compressors. Its electronic overload protects the motor from damage due to overcurrent, making it suitable for manufacturing and process industries.

What are the specifications of the SIEMENS 14DUB32AF motor starter?

The SIEMENS 14DUB32AF is a NEMA Size 1, non-reversing starter with three poles, rated 27 A, and a 110/120V AC coil. It includes a pilot light, one normally open auxiliary contact, and screw terminals. The electronic overload eliminates the need for thermal units.

Where to buy the SIEMENS 14DUB32AF motor starter worldwide?

You can source the SIEMENS 14DUB32AF motor starter worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct NEMA size for a SIEMENS motor starter?

Select the NEMA size based on the motor's full-load current and voltage. For the SIEMENS 14DUB32AF, NEMA Size 1 covers up to 27 A at 600V AC. Always match the coil voltage (e.g., 110/120V AC) to your control circuit and ensure the overload is set per motor nameplate data.
