KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 65°C NC, 10A 250V
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch designed to open a circuit at a calibrated temperature of 65°C (normally closed). Rated for 10A at 250V AC/DC, it provides reliable over-temperature protection for motors, transformers, power supplies, and heating elements.
Features
- Precision snap-action bimetallic disc ensures reliable trip at 65°C (±5°C typical).
- Rated for 10A resistive load at 250V AC/DC for robust circuit protection.
- Durable metallic shell construction for effective heat transfer and mechanical durability.
- Normally Closed (NC) configuration opens on temperature rise to cut power.
- Compact design with integral 7cm lead wires for easy installation.

The KSD9700/BK05-BB1D thermal switch utilizes a bimetallic disc mechanism housed in a metallic shell. When the ambient temperature reaches the factory-calibrated set point of 65°C, the disc snaps and physically opens the normally closed (NC) contacts, interrupting the current flow to the protected device. This mechanical action provides a failsafe, non-resettable method of over-temperature protection.
Its robust construction is suited for embedding in or mounting directly to heat-generating components like motor windings, transformer coils, or power electronic heatsinks. The metallic shell ensures rapid thermal response and long-term stability in demanding environments. After tripping, the switch remains open until the temperature drops significantly below the set point, allowing the protected system to cool before manual reset or replacement.
