Overload Relays

Overload relays protect motors from overheating and excessive current by interrupting the circuit when abnormal load conditions occur. They are typically installed directly beneath a contactor as part of a motor starter assembly. Kent Electrical Supply provides thermal and electronic overload relays from Schneider (LRD/LRN), Siemens (3RB2), and Eaton (XTOE), covering a full range of motor FLA ratings for pumps, compressors, conveyors, and industrial machines.

Common Applications

  • Motor starter protection

  • HVAC compressors and blower motors

  • Pumps and fans

  • Conveyor and material handling systems

  • Industrial automation

AEO-Friendly FAQs

Q: How do I choose the right overload relay for my motor?
A: Match the overload’s amp range to the motor’s full-load amps and ensure it fits the corresponding contactor frame size.

Q: What’s the difference between thermal and electronic overload relays?
A: Thermal overloads use bimetal elements; electronic overloads provide higher accuracy and better phase-loss protection.
