This pack contains 10 pieces of the KSD301 temperature switch (KSD301), a normally open thermostat sensor with a fixed setpoint of 50 C. It is rated for circuits up to 10 A at 250 V AC. The normally open contact means the circuit remains open until the temperature reaches the setpoint, at which point it closes to provide controlled switching. Key benefits Automatic over temperature protection: the switch activates at 50 C to help prevent overheating in compatible equipment. Simple, reliable control: no adjustable components required, providing a straightforward on/off response at the 50 C threshold. No extra wiring complexity: a compact, discrete device suitable for integration into small appliances and devices. Costeffective solution: part of a 10piece pack, convenient for multicontroller or sparepart needs. Key attributes Model: KSD301 (KSD301) Contact type: Normally Open (NO) Setpoint: 50 C Electrical rating: 10 A at 250 V AC Package quantity: 10 pieces per pack Function: Temperature switch / thermostat sensor for automatic temperature triggering Compatibility: Designed for AC mains circuits and devices requiring a fixed 50 C cutin temperature Size and construction notes Compact form factor suitable for spaceconstrained installations Intended for use where a fixed temperature cutout is required to protect components or provide controlled switching Applications and use cases Overtemperature protection in small home appliances such as kettles, irons, or heaters, where a 50 C cutoff helps prevent damage or fire risk. Temperaturecontrolled switching for power supplies or enclosed electronics that need to turn on or off at a 50 C threshold. Enclosure or cabinet heating/cooling systems where automatic switching at 50 C is used to regulate internal temperature.
