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.
ST-22 motor protector features snap action, automatic reset,
moisture/dust proof, and superior heat response and high grade
thermoplastic insulation, which can be used for overheat protection
of Electric Motors, Fluorescent Ballasts, Battery Chargers,
Transformers, Solenoids, Heating Pads, OA-machines and etc.
