ABB OT16ET3S Industrial Thermal Overload Relay

ABB OT16ET3S Industrial Thermal Overload Relay is a motor-protection device that helps prevent damage from overloads by interrupting current in motor circuits when elevated heat or excessive current is detected. Designed to work with ABB contactors, the OT16ET3S is part of ABB’s line of thermal overload relays and is intended for integration into low-voltage motor control schemes in industrial environments. The unit provides automatic protection for electric motors in a range of applications, offering a compact, robust solution that can be wired into standard control panels to coordinate protection with other ABB components. Common applications include fans, pumps, conveyors, and other motor-driven equipment found in manufacturing, processing, and HVAC systems. By including the OT16ET3S in an ABB-based protection scheme, engineers gain a cohesive, reliable means of safeguarding motors, reducing unplanned downtime and equipment wear.
