Pack of 10 normally closed KSD301 temperature switches, rated 10A / 250V, with a 90° setpoint. A compact, reliable thermal cutoff and control component for applications that need simple temperaturetriggered on/off switching. Why you need this Prevents overheating: the normally closed KSD301 opens the circuit at its set temperature to interrupt current flow and protect components and wiring. Simple temperature control: provides an automatic, direct electrical break at a defined temperature without additional electronics. Costeffective replacement: sold as a 10piece pack for repairs, spares, or batch projects. Key features and attributes Quantity: 10PCS per pack. Model: KSD301 / KSD301. Type: Normally closed temperature switch (closed at ambient, opens at setpoint). Electrical rating: 10A 250V. Setpoint: 90° (as specified in the product title). Functionality: opens when the set temperature is reached to interrupt current; closes again when temperature falls below the setpoint (typical behavior for KSD301 thermostats). Use: designed for direct on/off thermal switching and overtemperature protection in circuits within the listed rating. Compatibility and performance Use in circuits up to the listed 10A / 250V rating; check your device requirements and wiring before installation. Suitable as a dropin replacement for devices originally fitted with KSD301 type temperature switches with a 90° setpoint. Intended for electrical temperature control and protection where a normally closed, mechanical thermal switch is appropriate. Typical applications / use cases Overheat protection for small motors, transformers, or power supplies: opens the circuit when temperature rises to the setpoint to limit damage. Safety cutoff in appliances or devices: use in heaters, fans, or household electronics that require a simple thermal trip point. DIY repairs and prototypes: faulty KSD301 switches or add temperaturetriggered control to electronic projects. Installation and safety notes Verify the KSD301 90° setpoint and 10A/250V rating match your device requirements before replacing or installing. Follow proper electrical safety procedures and, if unsure, consult a qualified technician for installation. Do not exceed the listed electrical rating to avoid overheating or failure. This 10PCS pack of normally closed KSD301 10A250V KSD301 90Degree temperature switches offers a straightforward, proven thermal switching solution for protection and basic temperature control tasks.
