Product Description

The SCHNEIDER Overload Relay: Thermal Protection (MPN LR2K0312) is an IEC thermal overload relay with three poles, designed for use with TeSys Deca and TeSys K contactors. It features integrated bimetallic elements, eliminating the need for separate thermal units, and includes 1NO/1NC auxiliary contacts with a maximum signaling circuit voltage rating of 250V DC. The relay provides phase loss sensitivity and uses screw clamp terminals for secure wiring connections.

Frequently Asked Questions

What is the SCHNEIDER LR2K0312 overload relay used for?

The SCHNEIDER LR2K0312 is an IEC thermal overload relay that protects three-phase motors from overheating caused by overload or phase loss. It integrates bimetallic elements and 1NO/1NC auxiliary contacts, and is compatible with TeSys Deca and TeSys K contactors for industrial motor control applications.

What are the specifications of the SCHNEIDER LR2K0312 overload relay?

The SCHNEIDER LR2K0312 is a 3-pole thermal overload relay with 1NO/1NC auxiliary contacts, a maximum signaling circuit voltage of 250V DC, 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 K contactors.
