Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Contactor 43JG32AD used for?

This reversing magnetic contactor is used to control the forward and reverse rotation of three-phase AC motors in industrial applications such as conveyors, pumps, and hoists. It is designed for heavy-duty motor control in manufacturing, material handling, and process automation environments.

What are the specifications of the SIEMENS 43JG32AD contactor?

The SIEMENS 43JG32AD is a reversing NEMA magnetic contactor with 3 poles, NEMA Size 4, rated 135 A, and a coil voltage of 208V AC. It is built for reliable motor reversing in demanding industrial settings. For full electrical ratings, consult the manufacturer datasheet.

Where to buy the SIEMENS 43JG32AD contactor worldwide?

You can source the SIEMENS 43JG32AD reversing contactor through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact our team for pricing and lead time on this Siemens-branded component.

How to select the correct NEMA contactor size for a motor?

Select a NEMA contactor by matching its size and current rating to the motor's full-load amps and duty cycle. For reversing applications, ensure the contactor is rated for the motor's locked-rotor current. The SIEMENS 43JG32AD (NEMA Size 4, 135 A) suits motors up to approximately 75 HP at 480V. Always verify with local codes.
