    • JR28-36 thermal overload relay supports three-phase motor circuit safety by responding to abnormal overcurrent conditions.
    • Automatic power cut-off activates during abnormal overcurrent to help prevent motor burnout in industrial operation.
    • Choose from three adjustable current ranges: 17-25A, 23-32A, or 28-36A, based on the motor circuit requirements.
    • The 50/60Hz universal design supports electrical systems operating at either listed frequency.
    • A precise current adjustment dial helps set the relay to the required protection range for the connected motor circuit.
    • The sensitive thermal bimetal trip mechanism detects overload conditions and initiates circuit cut-off protection.
    • Dual protection covers motor overload and phase loss conditions within three-phase motor circuits.
    • The relay also addresses unbalanced three-phase current, providing an additional motor protection function.
