KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 75°C NC, 5A 250V
The KSD9700/BK05-BB1D is a normally closed (NC) bimetallic thermal switch rated for 5A at 250V AC/DC, designed to open its contacts at a calibrated 75°C setpoint. This metallic-shell protector integrates directly into electrical circuits for over-temperature cutoff in appliances, power supplies, and industrial controls.
Features
- 75°C Normally Closed (NC) bimetallic snap-action thermal switch
- Rated for 5A continuous current at 250V AC/DC
- Durable metallic shell construction for robust thermal conduction and mechanical protection
- Pre-calibrated, fixed-temperature setpoint for reliable overheat protection
- Compact design with integrated 7cm lead wires for easy installation

The KSD9700/BK05-BB1D is a bimetallic disc thermostat housed in a metallic shell, providing a reliable and cost-effective solution for over-temperature protection. Its normally closed contacts remain conductive under normal operating conditions but snap open when the local ambient temperature reaches the factory-set 75°C threshold, breaking the circuit to prevent damage.
This switch is designed for direct series connection within a power line, requiring no external power or signal conditioning. The metallic housing ensures fast thermal response and durability in demanding environments. It is ideal for integration into heating elements, transformers, motors, and other electrical equipment where space is constrained and automatic thermal cutoff is required.
