Miniature Earth Leakage Circuit Breaker

 

DZ47LE-63 series leakage circuit breaker is suitable for AC 50Hz, rated working voltage single pole two wires, two poles 230V, three poles, three poles four wires, four poles 400V, rated current up to 63A, used for indirect contact with people Protection, as well as overcurrent protection of lines for buildings and similar purposes. It can also provide protection against fires caused by ground faults that persist due to inoperative overcurrent protection devices. Leakage circuit breakers with overvoltage protection can also protect against overvoltage caused by grid faults.

 

This series of products has been increasingly used in low-voltage power distribution systems as backup protection for ground faults, direct contact, and indirect contact electric shock.

 

The product complies with GB 16917-1 and IEC 61009-1 standards.

 

 

 

 

Normal operating conditions and installation conditions

 

Ambient air temperature: the upper limit value does not exceed +40C, the lower limit value does not exceed -5C, and the average temperature value of 24 hours does not exceed +35C:
Note 1: The lower limit is -10C or -25C working conditions, the user must declare to the manufacturer when ordering;
Note 2: For working conditions where the upper limit exceeds +40C or the lower limit is lower than -25C, the user should negotiate with the manufacturer.
Installation site: the altitude does not exceed 2000m;
Atmospheric conditions: The relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40C. Higher relative humidity can be allowed at lower temperatures, for example, it can reach 90% at +20C. Occasional condensation due to temperature changes Lu shall take appropriate action;
Pollution level: Level 2;
Installation category: category 2 and category 3;
Installation conditions: the external magnetic field of the installation place should not exceed 5 times of the earth’s magnetic field in any direction. Generally, it is installed vertically, and the handle is upward for the power supply position. The tolerance of any direction is 2°, and there should be no significant shock and vibration at the installation place.
