Thermal cutoffs are temperature activated protection devices that open the circuit when a preset temperature is reached. They provide automatic, overtemperature protection for electrical and electronic equipment, helping prevent damage and reduce fire risk. Key benefits - Protects motors, transformers, heaters, power supplies and control circuits from overheating - Simple installation with compact form factors for easy integration - Automatic protection without user intervention - Available in multiple temperature ratings to suit different applications Function and operation - The device interrupts current flow when the heat level reaches its setpoint, preventing further temperature rise Compatibility and specifications - Suitable for a wide range of devices and assemblies that require overtemperature protection - Compact size supports use in limited spaces - Durable construction for high temperature environments; consult the datasheet for exact rating, lead length and termination style Performance - Fast response to rising temperature with consistent actuation at the rated setpoint - Stable performance across common ambient conditions and mechanical tolerances Use scenarios - In a toaster or coffee maker to prevent overheating of heating elements - In a PC power supply or USB charger to protect sensitive electronics - In a space heater, iron, or hair dryer to shut down before components reach unsafe temperatures Availability - Offered in a range of temperature ratings and configurations to fit different equipment and safety standards
