Product Description

The SCHNEIDER Overload Relay: Thermal Protection (MPN LR9D32) is an IEC thermal overload relay with integrated bimetallic elements, eliminating the need for separate thermal units. It features a 1NO/1NC auxiliary contact form, phase loss sensitivity, and a maximum voltage rating of 690V AC. This 3-pole relay is compatible with TeSys Deca contactors in the 1 to 32 Amp models.

Frequently Asked Questions

What is the SCHNEIDER LR9D32 overload relay used for?

The SCHNEIDER LR9D32 is an IEC thermal overload relay used to protect motors from overcurrent and phase loss. It integrates bimetallic elements and is compatible with TeSys Deca contactors in industrial automation, HVAC, and pumping applications.

What are the specifications of the SCHNEIDER LR9D32 overload relay?

The SCHNEIDER LR9D32 is a 3-pole thermal overload relay with a 1NO/1NC auxiliary contact, phase loss sensitivity, and a maximum voltage rating of 690V AC. It covers a current range of 6.4 A to 32 A and requires no separate thermal units.

Where to buy the SCHNEIDER LR9D32 overload relay worldwide?

You can source the SCHNEIDER LR9D32 overload relay worldwide through 3G Electric. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct SCHNEIDER overload relay for a motor?

To select the correct SCHNEIDER overload relay, match the relay's current range (e.g., 6.4 A to 32 A for the LR9D32) to the motor's full-load current. Ensure compatibility with your contactor series, such as TeSys Deca, and verify phase loss sensitivity is needed for your application.
