Pack of 10 KSD303 manual reset thermostat switches with a 100°C trip point and normally closed (NC) contacts. Each switch is designed to provide reliable thermal protection by cutting power when the temperature reaches 100°C and requiring a manual reset to restore operation. The devices are rated for 10A. Key benefits Reliable overheating protection: trips at 100°C to prevent damage to heating elements, motors, and electronics. Manual reset for deliberate control: must be reset by hand after tripping, reducing repeated nuisance trips. Easy replacement and scalability: ten pieces per pack provides ready supply for multiple machines or parallel installations. Simple integration: standard twoterminal, NC temperature switch suitable for retrofit or designs. Key specifications and attributes Model: KSD303 Pack quantity: 10 pieces Trip point: 100°C Contact type: Normally Closed (NC) Reset type: Manual reset Current rating: 10A Application type: Temperature switch / thermostat for electrical protection Functional overview At ambient temperatures below 100°C, the switch remains closed, allowing current to pass. When the temperature reaches 100°C, the switch activates and opens the circuit to stop power delivery. After cooling, the switch requires a manual reset to reclose the circuit and resume operation. Compatibility and applications Suitable for use in electrical appliances and equipment that require thermal protection at the 100°C level. Common use cases include heating elements, small household or industrial heaters, motors, power supplies, and equipment enclosures where overheating risk exists. Also applicable in DIY projects, 3D printers, and other devices that benefit from a simple, rearmable temperature cutoff. Use cases Overheat protection for compact heating devices such as coffee makers or space heaters, preventing damage and improving safety. Thermal protection in small motors or fans where excessive temperature could reduce performance or shorten life. Temperaturebased safety cutoff in power supplies or control panels that require a manual reset after tripping. Installation notes Ensure proper mounting and electrical wiring according to your device's design and safety standards. Verify that the application operates within the switch's 10A current rating and that the 100°C trip point is appropriate for your use case. Follow all relevant electrical codes and safety practices when replacing or installing the thermostats. This product aligns with the stated model, specifications, and features of the KSD303 series. The pack provides ten identical manual reset, normally closed temperature switches with a 100°C trip point and a 10A rating, suitable for a range of thermal protection applications.
