Thermal Overload Relay – 17–25A

1. Product Overview

Thermal Overload Relay – 17–25A is a precision motor-protection device designed to safeguard electric motors against overload and phase-failure conditions. It is primarily used in industrial control panels, motor starters, pumps, compressors, conveyors, fans, and other motor-driven equipment. Its adjustable 17–25A current range enables accurate protection across a broad range of motor applications, helping reduce overheating, unplanned downtime, and equipment damage. As a critical component of reliable electrical protection systems, it supports safer, more efficient, and cost-effective industrial operations.
