The KSD9700/BK05-BB1D is a bimetallic thermal cut-off switch housed in a metallic shell. It operates on a snap-action principle: a calibrated bimetallic disc deforms at its specific temperature threshold (120°C), rapidly opening the electrical contacts to break the circuit. This action provides fail-safe protection against overheating in enclosed or high-power environments.
Its metallic housing ensures robust mechanical protection and efficient heat transfer from the protected component to the sensing element. The switch is designed for direct series connection in the power line of the device it protects, making it a simple and effective solution for thermal management in appliances, power tools, lighting, and industrial control cabinets.
