1-Compact & Space-Saving: The disc design allows you to integrate it into small spaces such as motor housings, power supplies, and small appliances.
2-Snap-Action Mechanism: Provides quick and clean switching, that minimizes arcing while also extending contact life and reliability.
3-Manual Reset & Auto Reset Options:
1)Auto Reset: Automatically restores the circuit when the temperature returns to normal - great for unattended equipment.
2)Manual Reset: Requires user to reset, acts as a key safety lockout after the fault condition.
4-OEM Flexibility: We can provide a solution that works for your own ddesignthe mounting, terminals, set point (temperature) and housing.




Disc thermostats are commonly utilized for temperature regulating devices or as a safety cutout.
1- Transformers and Power Supplies: Protection from over-temperature for coils and cores
2- Electric Motors: Winding thermal protection is embedded
3- Household Appliances: Coffee makers, hair dryers, water kettles, microwaves
4- Battery packs: Thermal runaway protection in power tools and e-bikes
5- Industrial Equipment: Solenoids, valves, small heaters, and control cabinets
