10PCS Normally Open KSD301 (KSD301) 100°C Temperature Switch Thermostat Sensor — 10A 250V Overview A pack of ten KSD301 (also listed as KSD301) normally open temperature switch thermostats rated for 10A at 250V. Each unit is designed to trigger at 100 degrees (°C) and is intended for straightforward overtemperature control, protection, and temperaturetriggered switching in a wide range of electrical and appliance applications. Key Benefits Readytouse replacement parts: ten identical KSD301 thermostats in one pack—handy for repairs, spares, or multiple installations. Reliable temperaturetriggered protection: normally open configuration allows the switch to close at the rated temperature, giving a simple, mechanical means to activate or cut power when 100°C is reached. current capacity: rated for up to 10A at 250V, suitable for many household and light industrial circuits that need temperaturebased control. Simple and repeatable operation: mechanical switching provides consistent performance without external electronics. What this solves Prevents overheating by switching circuits when temperature reaches 100°C, protecting components and systems from thermal damage. Provides a compact, lowcomplexity solution for temperaturebased control where digital sensors or complex thermostats are not required. Supplies multiple units for projects or maintenance, reducing downtime and repeated ordering. Key Attributes Model: KSD301 / KSD301 Quantity: 10 pieces per pack Switch type: Normally Open (NO) — closes when the rated temperature is reached and reopens as it cools below the reset point Rated electrical performance: 10A at 250V AC Rated temperature: 100 degrees (°C) Function: Temperature switch / thermostat sensor for thermal control and protection Typical Applications / Use Cases Household appliances: or install temperature cutouts in devices such as small heaters, irons, or other appliances that require a 100°C safety or control switch. Industrial and hobby electronics: Use in motors, transformers, power supplies, or heating elements where a mechanical temperaturetriggered switch at 100°C is needed. and maintenance: Keep a pack of ten for service shops or DIY projects to quickly failed temperature switches or to equip multiple units with consistent thermal protection. Installation & Operation Notes Normally open: at ambient temperature the contacts are open; they close when the temperature reaches the specified 100°C trip point and will to the open state when cooled below the reset threshold. Use within the specified electrical rating (10A/250V) to ensure safe operation. Intended for use as a temperaturecontrolled switch; confirm suitability for your specific application and mounting method before installation. This pack of 10 KSD301 100°C normally open temperature switch thermostats offers a straightforward, reliable option for thermal protection and control where a mechanical switch rated at 10A/250V is required.
