 High Temperature Bimetal Thermostats 

H702 w/case > Online Tech Info
This bimetal type thermostat is able to perform at a high temperature of 400°C. For a disk-type bimetal thermostat, 250°C is considered to be upper limit because the disk cannot withstand the high temperature stress. We use a flat plate bimetal for the H series to achieve a temperature limit of 400°C. Use of a flat-bimetal and stainless steel spring creates an instant click activation without a spark, ensuring long life and high accuracy.
