    Motor Starter Overload Protectors

    Image of Product. Front orientation. Motor Starter Overload Protectors.
    Upgrade motor starters that use thermal overload protection with these solid-state overloads—they don't use heating elements, so enclosure ventilation and cooling is not required. All have a full-load amp adjustment dial to accommodate circuits with different full-load amp ratings.
    If the full-load amp rating is not shown on your motor’s faceplate, estimate the current rating (given the motor’s horsepower and voltage).
