Bakelite KSD301 50C Degree Normally Closed Temperature Controlled Switch Thermostat – 10A 250V

The 250V 10A Bakelite KSD301 Temperature Controlled Switch is a bimetal-disc thermostat designed for accurate temperature control and protection in electrical and heating systems. This 50C Normally Closed (NC) version keeps the circuit open under normal temperatures and closes only when the temperature reaches 50C. After cooling below the rated temperature, it automatically returns to its original open state. The Bakelite insulated housing ensures electrical safety and maintains stable thermal response, making it suitable for low-temperature activation systems, heaters, fans, and controlled temperature triggers.

Features:

1. 50C Normally Closed (NC) temperature activation
2. Automatically resets when the temperature falls
3. Bakelite insulated housing for enhanced electrical protection
4. Rated for 10A at 250V AC
5. Reliable bimetal sensing disc with fast thermal response
6. Long operating life with stable switching characteristics
7. Suitable for low-temperature activation and protection circuits
