Product Description

The SCHNEIDER Overload Relay: Thermal Protection (MPN LRD02) is a 3-pole IEC thermal overload relay designed for use with TeSys Deca contactors (9 to 38 Amp models). It features integrated bimetallic elements, eliminating the need for separate thermal units, and includes a 1NO/1NC auxiliary contact configuration with a maximum voltage rating of 690V AC. The relay offers phase loss sensitivity and uses screw clamp terminals for secure connections.

Frequently Asked Questions

What is the SCHNEIDER LRD02 overload relay used for?

The SCHNEIDER LRD02 is a 3-pole IEC thermal overload relay that protects motors from overheating due to overcurrent or phase loss. It integrates bimetallic elements and is designed for use with TeSys Deca contactors (9 to 38 Amp models) in industrial motor control applications.

What are the specifications of the SCHNEIDER LRD02 overload relay?

The SCHNEIDER LRD02 has 3 poles, a 1NO/1NC auxiliary contact form, a maximum voltage rating of 690V AC, and phase loss sensitivity. It uses screw clamp terminals and includes integrated bimetallic elements, so no separate thermal units are required. It is compatible with TeSys Deca contactors (9 to 38 Amp models).
