KSD301, 155°C Bimetal Thermostat Switch, Surface Mount Package

The KSD301 155°C Thermostat Switch is a snap-action bimetal thermal protector that activates at a preset temperature of 155°C, opening the circuit to protect electrical equipment from overheating. Once the temperature drops below a safe threshold, the contacts automatically return to the closed position. Designed for use in a wide range of temperature-sensitive applications, this thermostat switch is ideal for electric heaters, home appliances, power supplies, and battery packs. Its compact, flange-mount design makes installation quick and secure in most assemblies.
