Frequently Asked Questions

What is the SCHNEIDER LRD05L overload relay used for?

The SCHNEIDER LRD05L thermal overload relay protects motors from overheating caused by overcurrent or phase loss. It is used with TeSys Deca contactors (9 to 38 Amp models) in industrial motor control panels, conveyors, pumps, and HVAC systems. 3G Electric supplies this relay worldwide.

What are the specifications of the SCHNEIDER LRD05L overload relay?

The SCHNEIDER LRD05L is a 3-pole IEC thermal overload relay with integrated bimetallic elements, rated 0.63 A – 1 A. It has a 1NO/1NC auxiliary contact, phase loss sensitivity, and a maximum voltage rating of 690V AC. Terminal connection is via screw clamps. No external thermal units are required.

Where to buy the SCHNEIDER LRD05L overload relay worldwide?

3G Electric supplies the SCHNEIDER LRD05L overload relay to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this TeSys Deca-compatible thermal protection relay.

How to select the correct SCHNEIDER overload relay for a motor?

Select a SCHNEIDER overload relay by matching its current range to the motor full-load amps. The LRD05L covers 0.63 A – 1 A and includes phase loss sensitivity. Ensure compatibility with your contactor series (TeSys Deca for 9 to 38 Amp models). Always verify voltage rating (690V AC max) and auxiliary contact needs.
