KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 80C NC, 5A 250V
The KSD9700/BK05-BB1D is a metallic shell, normally closed (NC) thermal switch rated for 5A at 250V AC/DC, designed to open its contacts at a calibrated 80°C setpoint. It provides reliable over-temperature protection for power supplies, motors, transformers, and other electrical equipment.
Features
- Normally Closed (NC) bimetallic thermal switch opens at 80°C (±5°C typical).
- Rated for 5A continuous current at 250V AC/DC for robust circuit protection.
- Durable metallic shell construction ensures mechanical strength and thermal conductivity.
- Includes 7cm lead wires for easy integration into existing wiring harnesses.
- Compact form factor (approx. 9 x 7 x 1 cm) for space-constrained installations.

The KSD9700/BK05-BB1D is a bimetallic disc-type thermal cutoff switch housed in a metallic shell. Its operation relies on the differential thermal expansion of two bonded metals: when the calibrated temperature (80°C) is reached, the disc snaps open, breaking the electrical connection and interrupting current flow to the protected circuit. This simple, electromechanical design requires no external power, offering fail-safe protection.
Engineered for durability, the metallic housing provides excellent heat transfer from the monitored component to the internal bimetallic element, ensuring accurate and responsive tripping. The switch is suitable for a wide range of AC and DC applications where reliable, maintenance-free over-temperature protection is critical for safety and equipment longevity.
