Thermal overload relays protect three-phase electric motors from damage caused by sustained overcurrent conditions including mechanical overload, single-phasing, phase imbalance, and locked rotor faults. By sensing the heat generated through bimetallic strips, the overload relay trips the motor starter circuit before winding temperatures reach damaging levels — preventing costly motor burnouts. Used alongside a contactor as part of a direct-on-line or star-delta motor starter, thermal overload relays are adjustable to match the motor’s full-load current rating. Class 10 and Class 20 trip classes available. GoSwitchgear stocks thermal overload relays compatible with major contactor brands. In stock in Dubai — fast delivery across UAE.
