KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 110C NC, 10A 250V
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch rated for 10A at 250V AC/DC. It operates as a normally closed (NC) circuit breaker, opening at a fixed 110°C set point to protect electrical equipment from overheating in appliances, power tools, and industrial controls.
Features
- Fixed 110°C (230°F) snap-action thermal trip point, normally closed (NC) configuration.
- High-current 10A switching capacity at 250V AC/DC for robust circuit protection.
- Durable metallic shell construction for effective heat transfer and mechanical durability.
- Compact design with integrated 7cm lead wires for straightforward series installation.
- Reliable bimetallic disc actuator ensures repeatable operation and long service life.

The KSD9700/BK05-BB1D is a bimetallic disc thermal cutoff switch housed in a metallic shell. It functions as a non-resettable, one-shot thermal fuse in a normally closed configuration. When the ambient temperature surrounding its shell reaches the calibrated 110°C set point, the internal bimetallic disc snaps open, permanently breaking the electrical circuit to prevent overheating damage in the protected device.
Designed for direct series connection within a power line, its 10A/250V rating makes it suitable for monitoring transformers, motors, solenoids, and heating elements. The metal casing ensures rapid thermal response and robust physical protection, while the 7cm insulated leads facilitate secure wiring into control panels or appliance chassis.
