Scope of application

The DZ15LE series residual current circuit breaker is suitable for use in AC 50Hz, rated operating voltage up to 380V, and rated current up to 100A lines. It is used for indirect contact protection of people, as well as to prevent fire hazards caused by grounding fault currents due to equipment insulation damage. It can also be used to protect lines and motors from overload and short circuits, and can be used for infrequent switching of lines and infrequent starting of motors.
The product complies with GB 6829, GB 14048.2, IEC 60755, and IEC 60947 standards.

Model and its meaning


Normal working conditions and installation conditions
1. The upper limit of the surrounding air temperature shall not exceed+40 ℃, the lower limit shall not be lower than -5 ℃, and the average temperature value over 24 hours shall not exceed+35 ℃;
Note 1: For working conditions with a lower limit of -10 ℃ or -25 ℃, users must declare it to the manufacturer when placing an order;
Note 2: For working conditions where the upper limit value exceeds+40 ℃ or the lower limit value is below -25 ℃, the user should consult with the manufacturer.
2. The altitude of the installation site shall not exceed 2000m;
3. The relative humidity of the atmosphere should not exceed 50% when the ambient air temperature is+40 ℃. Higher relative humidity is allowed at lower temperatures, such as reaching 90% at+20 ℃. Appropriate measures should be taken for occasional condensation caused by temperature changes;
4. Pollution level: Level 3;
5. Installation category: Class III;
6. The external magnetic field of the installation site should not exceed 5 times the geomagnetic field in any direction;
7. Generally installed vertically, with the handle facing upwards as the power on position, and a tolerance of 2 ° in any direction;
8. The installation site should have no significant impact or vibration.
