KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 45C NC, 5A 250V
The KSD9700/BK05-BB1D is a metallic-shell, normally-closed (NC) thermal cutoff switch designed to protect electrical circuits and components from overheating by opening at a fixed 45°C setpoint. It is rated for 5A at 250V AC/DC, making it suitable for integration into power supplies, transformers, and small appliances.
Features
- Fixed 45°C normally closed (NC) thermal cutoff switch
- Rated for 5A at 250V AC/DC for robust circuit protection
- Durable metallic shell construction for reliable thermal conduction and mechanical strength
- Compact design with integrated 7cm lead wires for easy installation
- Single-use, non-resettable operation ensures fail-safe thermal protection

The KSD9700/BK05-BB1D is a bimetallic disc thermal cutoff (TCO) switch housed in a metallic shell. It operates on a snap-action principle: when the ambient temperature reaches its calibrated 45°C setpoint, the internal bimetallic disc snaps open, permanently breaking the electrical circuit to prevent overheating. This non-resettable, single-use design provides a fail-safe mechanism for thermal protection.
Its metallic housing ensures excellent thermal conductivity for accurate temperature sensing and offers robust physical protection against environmental factors. With a 5A current rating at 250V, it is engineered for direct series connection in AC or DC power lines of small motors, transformers, battery packs, and heating elements, providing a cost-effective and reliable safety solution.
