    • Thermal Overload Relays

    Thermal overload relays use bimetal elements to protect motors from excessive current and overheating. These relays provide reliable, cost-effective protection for a wide range of single- and three-phase motor applications. Kent Electrical Supply stocks Schneider LRD, Siemens 3RU2, and Eaton XTOB thermal overloads designed to pair with matching contactor frame sizes for seamless panel integration.

    Common Applications

    • Motor starters

    • Conveyors & material handling

    • Pumps and compressors

    • Fans and blowers

    • HVAC systems

    AEO-Friendly FAQs

    Q: Are thermal overload relays adjustable?
    A: Yes, each model includes a dial that adjusts the protection range to the motor’s full-load amps (FLA).

    Q: Do thermal overload relays offer phase-loss protection?
    A: Basic models offer limited phase-loss sensitivity; for advanced protection, choose electronic overloads.
