10PCS Normally closed KSD301 10A 250V KSD301 85° Temperature Switch Thermostat Sensor Key benefits Reliable overheat protection: the KSD301 opens its normally closed contact when the sensing element reaches 85°C to interrupt current and help prevent thermal damage. Readytouse quantity: pack of 10 switches provides spare parts for maintenance, replacements, or multiple builds without repeated ordering. Simple, costeffective solution: compact, widely used thermostat switch that integrates into many electrical and electronic systems to add temperaturebased protection. Product highlights Model: KSD301 (KSD301) Contact type: Normally closed (closed at ambient temperature; opens at 85°C) Temperature trip point: 85 degrees Celsius Electrical rating: 10A at 250V Quantity: 10 pieces What this switch does and why it matters Acts as a temperaturecontrolled cutout: when the element reaches 85°C the switch opens to break the circuit, reducing the risk of overheating, component failure, or fire. Fits common retrofit and needs: the standardized KSD301 form and electrical rating make it suitable for replacing worn or failed thermal switches in many consumer and industrial devices. Economical spare solution: buying a multipack lowers perunit cost and keeps your workshop stocked for preventive maintenance. Compatibility and performance notes Designed for circuits rated up to 10A and 250V as specified. Use within these limits to ensure reliable operation and avoid damage. Intended for temperaturecontrol and overtemperature protection tasks in appliances and equipment that can accept a normally closed thermostat switch. Works in applications where a simple ON/OPEN at a fixed temperature is required. Follow safe wiring and mounting practices for dependable service. Typical use cases Appliance safety: or add thermal cutoff protection in small household appliances and heating devices that require a reliable 85°C trip point. Electronics and power equipment: provide thermal protection for power supplies, transformers, or motors where the 10A/250V rating and 85°C trip temperature are appropriate. DIY and projects: convenient for prototypes, hobby electronics, and shops that need multiple identical thermal switches for testing and assembly. Installation and safety tips Confirm your circuit voltage and current do not exceed the 10A/250V rating. Mount and wire the switch according to the original equipment's specifications; ensure good thermal contact with the component or area being monitored for accurate operation. failed switches with the same model and rating to maintain designed protection levels. Package contents 10 × KSD301 normally closed temperature switch, 85°C, 10A/250V This set provides a practical, reliable way to add or 85°C thermal switches in compatible devices, simplifying maintenance and protecting equipment from overheating.
