YT 03 tiny 250v normally closed bimetal thermostat thermal switch protector
Key Features:
Miniature Size: Suitable for space-constrained applications.
High Voltage Rating: Capable of handling up to 250V AC.
Normally Closed Configuration: Power is conducted until triggered by temperature rise.
Precise Temperature Control: Accurate temperature sensing and response.
Reliable and Durable: Built to withstand harsh environments.
Wide Range of Applications: Suitable for various electronic devices and systems.
Temperature protection: YT03 thermal protector can control the temperature of the electronics precisely. When the electronics can’t work normally, which makes the ambient temperature be over high, the double metal reed of protector will disconnect from the silver contact to protect the electronics. When the temperature lows to the safe point, the contact will be connected again.
Overload current protection: YT03 thermal protector can control the over load current trip time precisely. If the current of motor or transformers is overload or the locked rotor current exceeds the set trip value, the protector will cut off the circuit instantly to protect the electronics, due to the inside electric heating element.
Wide Range of Applications: Suitable for various electronic devices and systems.
Applications:
Household appliances
Electronic devices
Industrial equipment
Automotive systems
