Product Description

The SCHNEIDER LRD332L is an IEC thermal overload relay with integrated bimetallic elements, designed for use with TeSys Deca contactors (40 to 65 Amp models). It features a 1NO/1NC auxiliary contact form, phase loss sensitivity, and screw clamp terminals, with a maximum voltage rating of 690V AC. This three-pole relay covers a current range of 23 A to 32 A and requires no external thermal units.

Frequently Asked Questions

What is the SCHNEIDER LRD332L overload relay used for?

The SCHNEIDER LRD332L is an IEC thermal overload relay that protects three-phase motors from overheating due to overload or phase loss. It is used in industrial motor control applications with TeSys Deca contactors (40 to 65 Amp models) to automatically disconnect power when current exceeds the 23 A to 32 A range.

What are the specifications of the SCHNEIDER LRD332L overload relay?

The SCHNEIDER LRD332L is a three-pole thermal overload relay with integrated bimetallic elements, rated for 23 A to 32 A. It has a 1NO/1NC auxiliary contact form, phase loss sensitivity, screw clamp terminals, and a maximum voltage rating of 690V AC. It requires no external thermal units and is compatible with TeSys Deca contactors (40 to 65 Amp models).

Where to buy the SCHNEIDER LRD332L overload relay worldwide?

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., 23 A to 32 A for the LRD332L) to the motor's full-load current. Ensure compatibility with your contactor series (TeSys Deca for this model) and verify voltage rating (690V AC max). For phase loss protection, choose a relay with phase loss sensitivity like the LRD332L.
