F Series Bimetal Snap-Action Temperature Switches

Microtherm Sentronic F Series Bimetal Snap-Action Temperature Switches are ideally suited for space-constrained installations under confined conditions. The switching principle consists of a central contact that opens or closes the application's circuit when triggered by temperature, using a thermo-bimetal snap-disc and pressure spring. These thermostats are shock and vibration tested, with a maximum switch temperature of +190°C. Additional features include thermal motor protection, temperature limiting or cut-off, high dimensional stability, and normally closed or normally open options. The series is available in a variety of design options, such as twin or triplet configurations and custom wire lengths. Applications for Microtherm Sentronic F Series switches include electric motors, single-phase to three-phase transformers, kitchen appliances, electronics, sensors, PCBs, welding devices, relays, and more.
