Includes 10 pieces of KSD301 normally closed temperature switches, each rated 10A / 250V with an 80° setpoint. Simple, reliable thermal protection and temperature switching for , replacement, and small control projects. Why you need it Prevents overheating by opening the circuit at a precise temperature (80°), protecting motors, heaters, transformers, and electronic assemblies. Costeffective replacement part or spare kit — ten identical switches for multiple devices or ongoing maintenance. Simple mechanical operation with a clear normallyclosed (NC) behavior: circuit is closed below the set temperature and opens at the setpoint to interrupt power. Key features and specifications Model: KSD301 / KSD301 Type: Normally closed (NC) temperature switch / thermostat sensor Temperature setpoint: 80° (80°C) Electrical rating: 10A / 250V Quantity: 10 pieces per pack Function: Opens the circuit when the set temperature is reached to provide thermal cutoff Performance and compatibility Rated to switch loads up to the specified 10A / 250V; suitable for many household and light industrial applications within that limit. Repeatable, mechanical switching action suitable for thermal protection and control where a single setpoint NC switch is required. Standard KSD301 form factor for compatibility with designs and replacements that accept this model. Typical applications Overheat protection for small motors, fans, and transformers — opens the circuit at 80° to prevent damage. Safety cutoff in heating appliances, soldering tools, and electric heaters where a single fixed trip temperature is required. Thermal control or protection in DIY projects, power supplies, and control panels as a simple thermostat or limit switch. Installation and usage notes Install the switch in series with the load you intend to protect so it can interrupt current when the setpoint is reached. Observe the electrical rating (10A / 250V) and verify compatibility with your application's voltage and current requirements. Follow standard safety practices: power off before installation, secure connections, and ensure the switch is mounted so it senses the correct temperature area. Package contents 10 × KSD301 normally closed temperature switches, 80° setpoint, 10A / 250V rating These KSD301 switches provide a straightforward, reliable thermal cutoff solution for repairs, replacements, and custom builds where a fixed NC thermostat at 80° is required.
