Bakelite KSD301 Temperature Controlled 85ºC Normally Closed Switch Thermostat - 10A 250V

The 250V 10A KSD301 Temperature Controlled Switch is a bimetal-activated thermostat designed for automatic temperature regulation and overheating protection. This 85ºC Normally Closed (NC) variant keeps the circuit closed under normal temperature conditions and opens when the preset cutoff temperature is reached. Once the temperature drops below the threshold, the switch automatically resets. With its durable metal housing and 10A current rating, it is suitable for appliances, power supplies, heating elements, motors, battery packs, and thermal safety circuits.

1. 85ºC Normally Closed (NC) temperature cutoff
2. Automatically resets after cooling
3. High current rating of 10A at 250V AC
4. Fast thermal response due to metal housing
5. Reliable bimetal disc mechanism for long life
6. Ideal for overheating protection and thermal control systems
