Product Description

The SIEMENS NEMA Magnetic Motor Starter is a non-reversing starter with electronic overloads, 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 1NO auxiliary contact. It uses screw terminals and requires no thermal units, as electronic overloads are integrated.

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 integrated electronic overload, making it suitable for pumps, conveyors, and compressors in manufacturing and processing plants.

What are the specifications of the SIEMENS 14DUB32AG motor starter?

The SIEMENS 14DUB32AG is a NEMA Size 1, non-reversing starter rated at 27 A with a coil voltage of 190-220/220-240V AC. It includes a pilot light, 1NO auxiliary contact, and screw terminals. Electronic overloads are integrated, so no thermal units are required.

Where to buy the SIEMENS 14DUB32AG motor starter worldwide?

You can source the SIEMENS 14DUB32AG motor starter through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your operations.

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 14DUB32AG, NEMA Size 1 supports up to 27 A. Match the coil voltage to your control circuit (e.g., 190-220/220-240V AC) and confirm the overload type—electronic overloads eliminate the need for separate thermal units.
