KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch 40°C Normally Open - 5A 250V
The KSD9700/BK05-BB1D is a metallic shell, snap-action thermal switch designed to open an electrical circuit at a precise 40°C setpoint. Rated for 5A at 250V AC/DC, it provides reliable over-temperature protection for motors, transformers, and power supplies.
Features
- Metallic shell construction for robust thermal conduction and durability.
- Precise 40°C (±3°C typical) normally-open (NO) snap-action switching.
- Rated for 5A at 250V AC/DC, suitable for a wide range of electrical loads.
- Compact form factor with 7cm lead wires for easy integration.
- Manual reset upon cooling for restored circuit operation.

The KSD9700/BK05-BB1D is a bimetallic disc thermostat housed in a metallic shell for optimal thermal response. The internal snap-action mechanism provides a crisp, reliable electrical break at the calibrated temperature threshold of 40°C, protecting sensitive components from heat damage. Its normally-open configuration ensures the circuit is interrupted upon reaching the setpoint.
This thermal switch is designed for direct mounting on heat sinks, motor housings, or within enclosures where ambient temperature monitoring is critical. The metallic shell ensures fast thermal transfer and mechanical robustness in industrial and consumer appliance environments. It operates on a simple, fail-safe principle requiring no external power, making it a reliable choice for safety-critical thermal cutoff applications.
