ST-12 thermal protector, ST-12 thermostat
ST-22 Bimetal Thermostat / ST-22 thermal protector
SEKI's bimetal thermostats are overheat protection devices for electric appliances. These reusable parts automatically reset when equipment cools down. If the fault persists, the motor protectors continue to provide automatic protection.
Our bimetal thermostat line includes two models: ST-12 and ST-22. The ST-12 model is designed for overheat protection in applications such as hair dryers, electric fan heaters, popcorn machines, electric ovens, and dish dryers. The ST-22 bimetal thermostat provides overheat protection for electric motors, fluorescent ballasts, battery chargers, transformers, solenoids, heating pads, and OA-machines.
Motor Protector Features: Snap action, automatic reset bimetals, moisture-proof, dust-proof, superior heat response
The ST-22 motor protector features snap action, automatic reset, moisture/dust proof construction, superior heat response, and high-grade thermoplastic insulation. It is ideal for overheat protection of electric motors, fluorescent ballasts, battery chargers, transformers, solenoids, heating pads, OA-machines and similar applications.
