The KSD9700/BK05-BB1D is a bimetallic disc-type thermal switch housed in a metallic shell. When the surrounding temperature reaches its calibrated setpoint of 105°C, the internal bimetallic element snaps, mechanically opening the normally closed contacts to interrupt the circuit. This provides a fail-safe method of cutting power to prevent overheating damage.
Its robust metallic housing ensures efficient heat transfer from the protected component to the sensing element and offers mechanical protection. The switch is designed for direct series connection with the load, making it a simple and cost-effective solution for over-temperature protection in a wide range of AC-powered equipment.
