10PCS KSD303 10A 65°C Manual Reset Thermostat Normally Closed Temperature Switch Reliable, simple overtemperature protection in a compact package Each pack contains 10 units of the KSD303 manual reset thermostat, a normally closed temperature switch rated for 10A with a 65°C trip point. Designed to open the circuit when the local temperature reaches 65°C and remain open until manually reset. This prevents automatic reenergizing and makes it easy to verify and correct the cause of overheating. Why customers choose this KSD303 thermostat Safety and control: The normally closed design keeps circuits active during normal operation and trips open at the set temperature to protect components from thermal damage. Manual reset for deliberate restart: Requires a user action to restore operation after a trip, reducing the risk of repeated automatic restarts into an unsafe condition. Costeffective pack of 10: Useful for repairs, projects, or stocking spare protection devices for multiple machines or devices. Key attributes Model: KSD303 Quantity: 10 pieces Trip temperature: 65°C Contact state: Normally closed (NC) Reset type: Manual reset Load rating: 10A (use within this current limit for reliable operation) How it works (simple and clear) At temperatures below 65°C the switch remains closed and allows current to flow. When local temperature reaches 65°C, the switch opens and cuts off current to the protected circuit. The switch stays open until manually reset by the operator, ensuring the system does not restart automatically before inspection or . Practical use cases Appliance protection: or add overtemperature protection in small household appliances that require a 65°C cutoff and a manual reset. Equipment and hobby electronics: Provide reliable thermal cutoff for motors, transformers, and other components where a 10A switching capacity is sufficient. Maintenance and : Keep a set of spares for industrial or commercial equipment maintenance where intentional restart after an overtemperature event is required. Installation and usage tips Mount the thermostat so it accurately senses the temperature of the component or area to be protected. Observe the 10A load rating; do not exceed the rated current. Make the manual reset easily accessible so technicians or users can inspect and reset after a trip. Follow local electrical codes and safe wiring practices when installing in powered equipment. This pack of 10 KSD303 65°C manual reset thermostats offers a straightforward, mechanical solution for overtemperature protection where a normally closed switch and intentional restart are preferred.
