Applications: Auto Reset Thermal Switch ST07 Working Principle
The core part of the thermal overload protector switch ST07 is a copper-nickel alloy bimetallic strip. When the ambient temperature reaches the cut-off temperature set by the product, the bimetallic strip of the automatically reset thermal switch for appliance ST07 will bend and deform to cut off the circuit to form protection. It will automatically reset when the temperature drops, allowing the circuit to reconnect.
Why ST07 Series Thermal Protectors
Each thermal overload protector switch ST07 rating has a bimetal disc designed and manufactured for the specific temperature rating. Each device is calibrated and checked for opening temperature. The core part of the bimetallic sheet is selected from the internationally renowned company EMS. The two-sheet molding is produced by ourselves, which is beneficial to quality control and full temperature inspection. The precise, consistent, and reliable performance is obtained by emphasizing quality.
