KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 140C NC, 5A 250V
The KSD9700/BK05-BB1D is a normally closed (NC) metallic shell temperature control switch rated for 5A at 250V AC/DC. It provides reliable thermal protection by opening its contacts at a fixed 140°C set point, suitable for integration into appliances, power supplies, and industrial equipment.
Features
- Fixed 140°C normally closed (NC) thermal cut-off switch.
- Rated for 5A continuous current at 250V AC/DC.
- Durable metallic shell construction for robust thermal and electrical isolation.
- Simple two-wire connection for series installation in power circuits.
- Designed for over-temperature protection in motors, transformers, and heating elements.

The KSD9700/BK05-BB1D is a bimetallic disc thermostat engineered for automatic circuit interruption upon reaching its calibrated temperature threshold. The switch operates in a normally closed (NC) configuration, maintaining circuit continuity until the internal temperature exceeds 140°C, at which point the bimetallic element snaps open to break the connection and halt current flow.
Housed in a sealed metallic shell, the switch offers excellent thermal conductivity for accurate sensing and provides electrical insulation and mechanical durability. Its design ensures a single-use or manual reset function (depending on variant), making it a critical safety component for preventing thermal runaway in electrical enclosures, motor windings, and power conversion units.
