Pack of 10 normally closed temperature switches KSD301 KSD301 with a 45Degree trip point. These thermostat switches are rated at 10A 250V and are designed for automatic temperature control and protection in a wide range of appliances and DIY projects. Each unit uses a normally closed contact that opens when the temperature reaches the set point, providing reliable overheat protection. Key benefits Reliable overheat protection: opens the circuit when the temperature reaches 45Degree to prevent damage or safety hazards. Normally closed default: circuit is complete at normal temperatures, enabling automatic protection without user intervention. Simple integration: designed for straightforward wiring in standard 10A, 250V load circuits. Compact and robust: small, epoxyencapsulated body suitable for tight spaces in household and industrial equipment. Value pack: 10 pieces per pack for easy replacement and stocking. Key attributes Model: KSD301 (KSD301) Contact configuration: Normally closed Trip temperature: 45Degree Electrical rating: 10A at 250V Package contents: 10 pieces Type: Temperature switch / thermostat sensor Construction: Epoxyencapsulated body for reliable operation in standard electrical environments Application context: suitable for temperaturecontrolled protection in appliances and equipment that require NC thermal switching Applications and use cases Overheat protection in small kitchen appliances such as coffee makers and electric kettles, where a rise in temperature triggers circuit interruption to prevent damage. Temperature control and safety shutdown for compact space heaters or heating elements, helping to maintain safe operating temperatures. Safety interlock or protection in DIY electronics, small motors, transformers, or other devices that require a normally closed thermal switch with a 45Degree trip point. How to use Install in series with the load so that current passes through the switch. Ensure the operating voltage does not exceed 250V and the current does not exceed 10A. Position the switch to be exposed to the target temperature for accurate trip detection. in sets as needed with the same model to maintain consistent protection across devices.
