Frequently Asked Questions

What is the SIEMENS NEMA Magnetic Contactor 40HP32AD used for?

This SIEMENS NEMA Size 3, 90 A contactor is used for switching motor loads and other inductive loads in industrial control panels, HVAC systems, and heavy machinery. It provides reliable non-reversing control of 3-phase motors up to 40 HP at 208V AC.

What are the specifications of the SIEMENS 40HP32AD contactor?

The SIEMENS 40HP32AD is a non-reversing NEMA magnetic contactor with 3 poles, NEMA Size 3, rated 90 A continuous at 208V AC. It is designed for motor control applications requiring dependable switching and long electrical life.

Where to buy the SIEMENS 40HP32AD contactor worldwide?

You can source the SIEMENS 40HP32AD contactor through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring your order arrives efficiently.

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. For a 40 HP motor at 208V AC, a NEMA Size 3 contactor rated 90 A is appropriate. Always verify the contactor's continuous current rating exceeds the motor nameplate amps.
