The KSD9700 NA 40°C thermal switch is a protection device designed for temperature control and overheat protection in electrical and electronic applications. This normally open (NA) thermal protector activates automatically when the temperature reaches 40 degrees Celsius, closing the circuit with high reliability and accuracy.
Thanks to its metal housing, the KSD9700 bimetal thermostat provides excellent thermal conductivity and fast response to temperature changes. It is supplied with a removable silicone sleeve, offering electrical insulation, mechanical protection and increased safety during installation.
This automatic thermal switch is suitable for applications such as power supplies, household appliances, electric motors, transformers, heating systems, fans and temperature-sensitive electronic equipment. Its compact design allows easy integration into confined spaces.
The KSD9700 NA 40°C is fitted with pre-tinned wires with a 70 mm lead length, enabling a quick and secure connection. The device features automatic reset operation, returning to its original state once the temperature drops below the switching point.
This thermal protection thermostat combines reliability, thermal accuracy and long service life, making it an efficient solution for applications requiring a 40°C normally open thermal switch with industrial-grade performance.
