Product Description

The SIEMENS NEMA Magnetic Motor Starter: Reversing (SKU 44N908, MPN 22JUH32AH) is a three-phase reversing starter with electronic overloads, NEMA Size 4, rated 135 A. It features a 380-440/440-480V AC coil, screw terminals, a 1NO auxiliary contact, and a pilot light. Thermal units are not required as the overload is electronic.

Frequently Asked Questions

What is the SIEMENS NEMA reversing magnetic motor starter used for?

This SIEMENS NEMA reversing magnetic motor starter is used to control the forward and reverse rotation of three-phase industrial motors. It is commonly applied in conveyors, hoists, and pumps where direction changes are required. The electronic overload protects the motor from damage due to overcurrent.

What are the specifications of the SIEMENS 22JUH32AH reversing starter?

The SIEMENS 22JUH32AH is a NEMA Size 4 reversing starter rated 135 A with 3 poles. It operates on a 380-440/440-480V AC coil voltage and includes a 1NO auxiliary contact, screw terminals, and a pilot light. Electronic overload protection eliminates the need for thermal units.

Where to buy the SIEMENS 22JUH32AH reversing starter worldwide?

You can source the SIEMENS 22JUH32AH reversing starter worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

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

Select the NEMA size based on the motor's full-load current and voltage. For the SIEMENS 22JUH32AH, NEMA Size 4 is rated 135 A, suitable for larger three-phase motors. Always match the coil voltage (e.g., 480V AC) to your control circuit and ensure the starter includes proper overload protection.
