Product Description

The SCHNEIDER LRD22L is an IEC thermal overload relay with integrated bimetallic elements, designed for use with TeSys Deca contactors (25 to 38 Amp models). It features a 1NO/1NC auxiliary contact form, a maximum voltage rating of 690V AC, and phase loss sensitivity. The relay includes screw clamp terminals and requires no external thermal units.

Frequently Asked Questions

What is the SCHNEIDER LRD22L overload relay used for?

The SCHNEIDER LRD22L is an IEC thermal overload relay that protects motors from overheating due to overload or phase loss. It is used with TeSys Deca contactors (25 to 38 Amp models) in industrial motor control panels, conveyors, pumps, and HVAC systems.

What are the specifications of the SCHNEIDER LRD22L overload relay?

The SCHNEIDER LRD22L is a 3-pole thermal overload relay with a current range of 17 A to 24 A, 1NO/1NC auxiliary contacts, and a maximum voltage rating of 690V AC. It includes integrated bimetallic elements for phase loss sensitivity and uses screw clamp terminals.

Where to buy the SCHNEIDER LRD22L overload relay worldwide?

3G Electric supplies the SCHNEIDER LRD22L overload relay worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for a quote and lead time on this TeSys Deca-compatible relay.

How to install the SCHNEIDER LRD22L overload relay?

Mount the SCHNEIDER LRD22L directly onto a compatible TeSys Deca contactor (25 to 38 Amp models). Connect the motor leads to the screw clamp terminals, set the dial to the motor full-load current (17 A to 24 A), and verify phase loss sensitivity is enabled. Follow local electrical codes.
