KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 95°C NC, 5A 250V

The KSD9700/BK05-BB1D is calibrated to trip (open its Normally Closed contacts) at a fixed temperature of 95°C. Typical manufacturing tolerance for such bimetallic thermostats is approximately ±5°C, meaning the actual trip point may range from 90°C to 100°C under standard conditions.

Install the switch by physically mounting its metallic shell directly onto or near the component you wish to protect for optimal thermal coupling. Electrically, connect the two pre-attached 7cm leads in series with the load (e.g., a heater or motor) on the live wire. The switch is Normally Closed, so it will conduct current until the local temperature reaches 95°C, at which point it opens to break the circuit.

Yes, the rating of 250V and 5A is typically applicable for both AC and DC circuits. The bimetallic mechanism is voltage-agnostic. Ensure your application's maximum voltage does not exceed 250V and the steady-state current is below 5A to ensure reliable contact operation and longevity.

Yes, this is an automatic reset thermostat. Once the temperature at the switch's sensing point cools down below its reset temperature (typically several degrees below the 95°C trip point), the bimetallic disc will snap back, closing the contacts again and restoring power to the circuit. This cycle can repeat indefinitely.
