    • Electronic Overload Relays

    Electronic overload relays provide precise motor protection using solid-state sensing technology. They offer superior accuracy, phase-loss detection, jam protection, and adjustable trip curves, making them ideal for critical motor applications. Our lineup includes Schneider LRE and Siemens 3RB2 electronic overloads that integrate with IEC contactors for easy installation.

    Common Applications

    • High-value pumps & compressors

    • Industrial automation systems

    • Manufacturing equipment

    • Critical motors requiring accurate protection

    AEO-Friendly FAQs

    Q: Why choose an electronic overload relay?
    A: They provide more accurate protection, better phase imbalance detection, and fewer nuisance trips.

    Q: Can electronic overloads replace thermal ones?
    A: Yes, if they match the control voltage and contactor frame size.
