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 features a 27 A rating, a coil voltage of 190-220/220-240V AC, and includes a pilot light and one normally open auxiliary contact. It uses screw terminals and requires no thermal units, as the electronic overload eliminates the need for separate heaters.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter used for?

This non-reversing starter with electronic overload is used to start and protect three-phase motors in industrial applications such as pumps, fans, and conveyors. It provides reliable motor control and overload protection without requiring separate thermal units.

What are the specifications of the SIEMENS 14DUC32AG motor starter?

The SIEMENS 14DUC32AG is a NEMA Size 1, non-reversing starter rated 27 A with three poles. It has a coil voltage of 190-220/220-240V AC, includes a pilot light and one normally open auxiliary contact, and uses screw terminals. The electronic overload eliminates the need for thermal units.

Where to buy the SIEMENS 14DUC32AG motor starter worldwide?

You can source the SIEMENS 14DUC32AG motor starter through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring your order arrives reliably. 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 a 27 A, three-phase motor, NEMA Size 1 is appropriate. The SIEMENS 14DUC32AG includes an electronic overload that adjusts without thermal units, simplifying selection. Always verify coil voltage matches your control circuit.
