Thermal overload relay series

introduction

Thermal overload relays are core components for motor protection. They detect abnormal current through bimetallic strips or electronic sensors, and then delay the disconnection of the overload circuit to prevent equipment damage. They support adjustable setpoints and multi-pole configurations, are compatible with AC/DC systems, and are suitable for industrial machinery, fans, pumps, and other applications, providing precise overload protection and long-life operation.
