Instructions
Molded case circuit breaker is suitable for AC 50 Hz, rated voltage 690 V and below, rated current to 1250 A circuit. Generally used for distribution, circuit breakers with rated current of 1250 A or below can also be used as motor protection. Under normal circumstances, circuit breakers can be used for the infrequent switching of lines and the infrequent starting of motors.
work environment
1. Temperature: - 5 ~+40ºC, average temperature within 24 hours does not exceed + 35ºC.
2. Relative humidity: when the maximum temperature is 40ºC, it is not more than 50%. Higher humidity is allowed at lower temperature.
3. Elevation below 2000 meters.
4. there is no explosive dangerous medium in the air and no corrosive metal, destroying insulating gas and conductive dust.
5. there is no snow or rain, the pollution level is Grade 3.
Parameter
6. series of mechanical adjustable circuit breakers
