Product Description

The SCHNEIDER Overload Relay: Thermal Protection (MPN LR2K0305) is an IEC thermal overload relay designed for use with TeSys K contactors. It features 1NO/1NC auxiliary contacts, a maximum signaling circuit voltage rating of 250V DC, and phase loss sensitivity. The relay includes integrated bimetallic elements, eliminating the need for separate thermal units, and uses screw clamp terminals for connection.

Frequently Asked Questions

What is the SCHNEIDER LR2K0305 overload relay used for?

The SCHNEIDER LR2K0305 is an IEC thermal overload relay that protects motors from overheating caused by sustained overcurrent or phase loss. It is designed for use with TeSys K contactors in industrial control panels, conveyors, pumps, and HVAC equipment where reliable thermal protection is required.

What are the specifications of the SCHNEIDER LR2K0305 overload relay?

The SCHNEIDER LR2K0305 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 includes integrated bimetallic elements, uses screw clamp terminals, and is compatible with TeSys K contactors. No separate thermal units are needed.

Where to buy the SCHNEIDER LR2K0305 overload relay worldwide?

You can source the SCHNEIDER LR2K0305 overload relay through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact our team for pricing and lead time on this TeSys K compatible relay.

How to select the correct SCHNEIDER overload relay for a TeSys K contactor?

To select the correct SCHNEIDER overload relay for a TeSys K contactor, verify the motor full-load current range matches the relay setting, confirm the contactor model is from the TeSys K series, and ensure the auxiliary contact configuration (1NO/1NC) suits your control circuit. The LR2K0305 includes integrated bimetallic elements and phase loss sensitivity.
