ABB OT125FL3 Industrial Thermal Overload Relay

ABB OT125FL3 is a three-pole switch-disconnector rated for 125 A, designed to isolate circuits in low-voltage motor control and distribution applications. The model is part of ABB's OT125FLx family and is referenced in ABB catalogs and distributor listings as a 3P, 125 A disconnect suitable for panel-mounted isolation in industrial panels and equipment. It provides independent phase separation via a mechanical operating mechanism, enabling safe maintenance and fault isolation in three-phase systems. In typical installations, the OT125FL3 is used alongside ABB contactors and overload protection devices to form a complete motor-control solution for starting, stopping, and protecting three-phase motors.
