Thermal Cutoffs are compact safety devices that open the circuit when a preset temperature is reached, protecting equipment from overheating and reducing fire risk. Key benefits - Protects appliances and wiring from heat damage - Simple in-line installation with existing wiring - Provides reliable one-time protection to prevent continued operation after overheating - Small form factor that fits in crowded assemblies How it works - An internal fusible element melts at the set temperature, permanently interrupting current to stop heat buildup Key attributes - Function: temperature-activated circuit interruption - Compatibility: designed to replace similar one-shot thermal cutoffs in many motors, heaters, power supplies, and other electrical devices - Size: compact form factor suitable for tight spaces and inline wiring - Material: durable metal body with sealed construction for high temperature environments - Performance: rapid response at the specified temperature and stable operation over the device life Applications - In small appliances such as hair dryers, irons, and coffee makers to guard against overheating - In battery chargers, power adapters, and portable power packs to prevent thermal runaway during operation - In 3D printers, hotends, and heated beds to protect against cooling failures or sensor faults Installation notes - Replace with a thermal cutoff rated for a matching temperature point - Install in series with the load and follow standard wiring practices and safety guidelines
