Description
The Schneider Electric (Square D) 9065SF220 Thermal Overload Relay is used to monitor the current flowing through the motor and to interrupt operation when there is overload in the equipment of HVAC systems. It is intended to operate in a 15-45A range and is sensitive to sustained overcurrent to trigger a trip, and avoid overheating and damage. It works based on a thermal sensing system that reacts to changes in current and initiates switching behavior. It is mounted in control panels or starter assemblies and is connected to contactors, and control circuits. .
