Product Description

1. Application scope

This product specification is applicable to thermal fuses that exceed thermal protection. When this product is used for other purposes, please contact us.
Hairdryer, soldering iron, dishwasher, rice cooker, water dispenser, heater, etc

1. Electrical characteristics:

2.1 Rated voltage: AC/DC 250V/125V
2.2 Rated current: AC/DC 10-20A
2.3 Disconnect temperature accuracy:+0 ° C, -5 ° C

1. 1. Temperature point production range: 70 ° C~280 ° C

 

1. 1. 1. To prevent damaging disconnection, thermal fuses should be used in environments (including the self-heating of the body) below the holding temperature Th ° C. (Th: Maintain at rated load for 168 hours, without body melting or temperature drift)
      2. In addition, after the body is disconnected in the application, the overload temperature should not exceed the maximum temperature (extreme speed H). Excessive overload temperature may cause the body to withstand voltage and break down, leading to re conductivity. For functional bodies, the correct overload temperature for operation should be determined through testing in the application.
      3. For progress information on the application and installation of this ontology, please contact our engineers.

 

1. 1. Temperature characteristic parameters:

Note: Maintain temperature (Th): The temperature at which the body can withstand the rated current and voltage of continuous connection without disconnection for 168 hours within (Th), exceeding the limit of service life or disconnection.

Maximum temperature (H): After disconnection, the body can maintain the maximum withstand temperature of the disconnected circuit.
