Thermal Overload Relay – 23–32A

1. Product Overview

The Thermal Overload Relay – 23–32A is a precision motor-protection device designed to safeguard electric motors against sustained overcurrent and thermal overload conditions. It is widely used in industrial motor starters, control panels, pumps, compressors, conveyors, fans, and other motor-driven equipment. Its adjustable 23–32A current range enables flexible protection across different motor loads while helping reduce downtime and equipment damage. For industrial buyers, it provides a practical, cost-effective solution for improving motor protection, operational reliability, and maintenance efficiency.
