DZ47-63 Miniature Circuit Breakers
1. Application
DZ47-63 Miniature Circuit Breakers are mainly used in AC 50Hz circuit with rated voltage 230V/400V, rated current up to 63A or less, and rated operating breaking capacity no more than 4500A power distribution system, protection of control circuit against short circuit and overload current fault. And also have circuit control and isolation function.

3. Working and the installing condition
3.1 Ambient max temperature is no more than +40℃, minimum temperature is not less than -5℃. No more than +35℃ within 24 hours;
3.2 altitude is no more than 2000m;
3.3 when the highest temperature reaches 40℃ the air relative humidity of the installing place can't exceed 50%, when in the low temperature it will have the relative higher humidity. When the average largest relative humidity in the most humiddest it is month no more than 90%, then the monthly-average temperature is no more than 25℃. We must take measure of the dew in the surface of the product due to the
temperature;
3.4 installing method: Din rail embedded
