Product Description

The SIEMENS NEMA Magnetic Motor Starter is a non-reversing starter with electronic overloads, designed for three-phase applications. This NEMA Size 3-1/2 unit (MPN 14IUH32AA) features a 115 A rating, a dual-voltage coil (110-120/220-240V AC), and includes a pilot light and one normally open auxiliary contact. It uses screw terminals and requires no thermal units.

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 pumps, fans, and conveyors. Its electronic overload provides adjustable motor protection, and the pilot light indicates operational status. It is suitable for heavy-duty environments requiring reliable motor control.

What are the specifications of the SIEMENS 14IUH32AA motor starter?

The SIEMENS 14IUH32AA is a NEMA Size 3-1/2 non-reversing starter rated at 115 A for three-phase motors. It features a dual-voltage coil (110-120/220-240V AC), one normally open auxiliary contact, a pilot light, and screw terminals. Electronic overloads are included, so no separate thermal units are required.

Where to buy the SIEMENS NEMA Size 3-1/2 starter worldwide?

You can source the SIEMENS NEMA Size 3-1/2 starter (MPN 14IUH32AA) 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; we supply genuine Siemens components for industrial motor control.

How to select the correct coil voltage for a SIEMENS motor starter?

Select the coil voltage to match your control circuit supply. The SIEMENS 14IUH32AA accepts dual voltage (110-120/220-240V AC), allowing flexibility. For other Siemens starters, verify the coil voltage rating on the nameplate. Using the wrong voltage can cause coil failure or improper operation. Always consult the wiring diagram before installation.
