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 4 unit features a 135 A rating, a 110/120V AC coil, and includes a pilot light and one normally open auxiliary contact. It utilizes screw terminals for connection and does not require thermal units due to its electronic overload design.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter used for?

This SIEMENS NEMA Magnetic Motor Starter is used for starting and stopping three-phase motors in industrial applications. It is a non-reversing starter with an electronic overload, suitable for controlling motors up to 135 A. Common uses include pumps, fans, conveyors, and compressors in manufacturing and processing plants.

What are the specifications of the SIEMENS NEMA Magnetic Motor Starter 14JUH32AF?

The SIEMENS NEMA Magnetic Motor Starter 14JUH32AF is a non-reversing, three-pole starter with NEMA Size 4 rating and 135 A capacity. It features a 110/120V AC coil, screw terminals, a pilot light, and one normally open auxiliary contact. The electronic overload eliminates the need for separate thermal units.

Where to buy the SIEMENS NEMA Magnetic Motor Starter 14JUH32AF worldwide?

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 SIEMENS starter like the NEMA Size 4, rated 135 A, ensure the motor's FLA does not exceed the starter's ampacity. Also match the coil voltage (e.g., 110/120V AC) to your control circuit. Consult the motor nameplate and Siemens selection guidelines for proper sizing.
