DZ47LE series leakage circuit breakers

Applicable scope

DZ47LE series leakage circuit breaker is suitable for use in ac frequency 50 Hz, rated voltage 230 V-400 V and rated current to 100 A line, people used to indirect contact with protection, as well as on buildings and similar USES the lines over current protection. Can also be used to because the device over current protection movement and persistent ground fault caused by the fire for protection. The leakage circuit breakers with overvoltage relaying protection for power grid failure because caused by the high voltage protection.

This series of products in low voltage distribution system is increasingly being used as a ground fault and direct contact, indirect contact with shock backup protection.

This product compound GB16917 and IEC61009 standards.

Model and its meaning

 

DZ47LE circuit breaker normal working conditions and installation conditions

1, air temperature around the upper not more than + 40 ℃, limit not less than 5 ℃, the average temperature and 24 hours is not more than + 35 ℃;

Note 1: the lower limit for-10 ℃ or-25 ℃ working conditions, in order to the manufacturer must be user statement;

Note 2: limits on more than 40 ℃ or limit + 25 ℃ lower than-the working conditions, the user and factory consultation.

2, the location of the elevation not more than 2000 M;

3, air relative humidity in the air temperature around for + 40 ℃ at no more than 50%, in the low temperature can allow a higher relative humidity, listed as in + 20 ℃ played 90%, but due to temperature change generated occasionally any proper measures must be taken to;

4, pollution level: level 2;

5, installation category: class II and III;

6, installation place outside of the magnetic field not be any direction of the geomagnetic field five times;

7, general perpendicular installation, handle up to turn on the power position, any direction allow error 2 degrees;

8, installation area should be no significant impact and vibration.

Structure characteristics

No leakage circuit breaker mainly by the zero sequence current transformer, electronic component board, leakage tripping device, and contacts operator and the plastic covering etc.
