ABB OHY145L12 Industrial Overload Relay For Three Phase Motors And Starters

The ABB OHY145L12 is a three-phase motor overload relay in ABB's OHY family, designed to protect three-phase motors and starters in industrial control panels. Used with compatible ABB contactors and starters, this 3-pole relay monitors motor current and interrupts the control circuit when an overload condition is detected, helping prevent overheating and equipment damage. The OHY145L12 is part of ABB's line of electronic overload relays that provide thermal overload protection for three-phase motors in a compact, panel-mounted package. Typical applications include pumps, fans, conveyors, and other continuous-load motors in manufacturing and processing environments where reliable overload protection and coordination with starting devices are essential. When integrating this model, verify compatibility with the specific ABB control gear to ensure proper protection for your motor and starter assembly.
