Тепловой контакт перегрузки Caterpillar 3089788

The Thermal Overload Contact is installed within a motor starter to protect the motor from overheating caused by excessive current. It monitors heat conditions created by overload situations and responds when the temperature rises beyond safe operating limits. It interrupts the control circuit when abnormal heat is detected, stopping motor operation before damage can occur. It helps prevent winding failure, insulation breakdown, and unexpected equipment shutdown caused by prolonged overload conditions.Attributes:• Protects motor windings from overheating damage.• Helps improve overall system reliability.• Supports reliable operation of motor starter systems.Applications: The Thermal Overload Contact is located inside the motor starter assembly, where it monitors heat generated by motor current and interrupts the control circuit to stop operation when overload conditions cause excessive temperature rise.
