SEKI's bimetal thermostats are overheat protection devices for electric appliances and they are reusable parts that are reset when equipment cools. If the fault still exists, the motor protectors continue to automatically protect the equipment.
There're two models in our bimetal thermostat, ST-12 & ST-22. ST-12 is used for overheat protection for hair dryer, electric fan heaters, popcorn machines, electric ovens, dish dryers and etc. ST-22 bimetal thermostat is used for overheat protection for electric motors, fluorescent ballasts, battery chargers, transformers, solenoids, heating pads, OA-machines and etc.
