The SIEMENS 40IP32AA is a non-reversing NEMA magnetic contactor used for switching motor loads and other inductive circuits in industrial automation, HVAC, and pump control applications. It provides reliable on/off control for three-phase equipment up to 115 A continuous current.

What are the specifications of the SIEMENS 40IP32AA contactor?

The SIEMENS 40IP32AA is a non-reversing, 3-pole NEMA magnetic contactor rated NEMA Size 3-1/2 with a continuous current rating of 115 A. It operates on a 115 VAC coil voltage and is designed for heavy-duty industrial motor control applications.

Where to buy the SIEMENS 40IP32AA contactor worldwide?

You can source the SIEMENS 40IP32AA 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 NEMA contactor.

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

Select a NEMA contactor size based on the motor's full-load current and voltage rating. For a 115 A continuous load, a NEMA Size 3-1/2 contactor like the SIEMENS 40IP32AA is appropriate. Always verify coil voltage matches your control circuit and consider ambient temperature derating per NEC guidelines.
