Temperature switch "NC contact" 250V AC/DC

Product information "Temperature switch "NC contact" 250V AC/DC"

Temperature switch "normally closed contact" which opens a circuit when the nominal temperature is exceeded (selectable via the selection list above), thereby stopping the desired process (heating, cooling, etc.). The switch closes again automatically when the temperature falls below the temperature due to cooling. Attention: "Normally closed" means that the circuit is interrupted at the selected temperature. If you want a switch that closes the circuit, it is a "normally open contact". We also have the temperature switch as a "normally open contact" for the reverse process for all temperature ranges in the store. Translated with www.DeepL.com/Translator (free version)

This switch is used in practice to protect devices or components against overheating. Also suitable for installation in switch cabinets and for direct mounting on motors, transformers and semiconductor heat sinks.
