Product Description

The SIEMENS NEMA Magnetic Motor Starter: Reversing (SKU 44N838, MPN 22CUB32AA) is a three-phase reversing starter with electronic overload protection, NEMA Size 0, and an 18 A rating. It features a 110-120/220-240V AC dual-voltage coil, screw terminals, a 1NO auxiliary contact, and a pilot light for signaling. No thermal units are required as the overload is electronic.

Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Motor Starter: Reversing used for?

This reversing starter is used to control the forward and reverse rotation of three-phase AC motors in industrial applications such as conveyors, hoists, and pumps. It provides electronic overload protection to prevent motor damage from overcurrent conditions, making it suitable for demanding manufacturing and processing environments.

What are the specifications of the SIEMENS 22CUB32AA reversing starter?

The SIEMENS 22CUB32AA is a NEMA Size 0, three-phase reversing starter rated at 18 A. It features a dual-voltage coil (110-120/220-240V AC), screw terminals, a 1NO auxiliary contact, and a pilot light for signaling. Electronic overload protection eliminates the need for thermal units.

Where to buy the SIEMENS 22CUB32AA reversing starter worldwide?

You can source the SIEMENS 22CUB32AA reversing starter 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 your motor control needs.

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

Select the NEMA size based on the motor's full-load current and voltage. For a NEMA Size 0 starter like the SIEMENS 22CUB32AA, it is rated for up to 18 A at 600V AC. Always match the starter's ampere rating to the motor nameplate and ensure the coil voltage matches your control circuit. Consult Siemens documentation for precise sizing.
