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 14DUA32AF) features a 110/120V AC coil, 27 A rating, 1NO auxiliary contact, screw terminals, and a pilot light. Thermal units are not required as the overload 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. It provides overload protection via its electronic overload, making it suitable for pumps, conveyors, fans, and compressors in manufacturing, HVAC, and material handling systems.

What are the specifications of the SIEMENS 14DUA32AF motor starter?

The SIEMENS 14DUA32AF is a NEMA Size 1, non-reversing starter with 3 poles, rated 27 A. It has a 110/120V AC coil, 1NO auxiliary contact, screw terminals, and a pilot light. The electronic overload eliminates the need for thermal units. It is designed for three-phase applications.

Where to buy the SIEMENS 14DUA32AF motor starter worldwide?

You can source the SIEMENS 14DUA32AF motor starter through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this Siemens-branded starter.

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

Select the NEMA size based on the motor's full-load current and voltage. For the SIEMENS 14DUA32AF, NEMA Size 1 handles up to 27 A. Match the coil voltage (110/120V AC) to your control circuit. Ensure the starter's pole count and phase match your motor. Consult Siemens documentation for exact sizing.
