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 relay, making it suitable for pumps, conveyors, fans, and compressors in manufacturing, HVAC, and process industries.

What are the specifications of the SIEMENS NEMA Magnetic Motor Starter 14IUH32AG?

This non-reversing starter has NEMA Size 3-1/2, 3 poles, and a 115 A rating. It operates on a 190-220/220-240V AC coil voltage for three-phase power. It includes a pilot light, 1NO auxiliary contact, and screw terminals. No thermal units are required as it uses an electronic overload.

Where to buy the SIEMENS NEMA Magnetic Motor Starter 14IUH32AG worldwide?

You can source the SIEMENS NEMA Magnetic Motor Starter 14IUH32AG from 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.

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

Select the NEMA size based on the motor's full-load current and voltage. For a 115 A, three-phase motor, NEMA Size 3-1/2 is appropriate. Ensure the coil voltage matches your control circuit (e.g., 190-220/220-240V AC). Always verify the starter's ampere rating exceeds the motor's FLA.
