Application

CSDM5DC Series DC Moulded Case Circuit Breaker is specially designed for DC electrical system with rated voltage up to DC1500V and rated current up to 800A. The Circuit Breaker can reliably protect the electrical system when the electrical loading of the system is overloaded or short circuited, specially for PV and wind power application.

Meet the standard:

Normal Working Conditions and Installation Conditions

•The elevation of the installation site can't exceed 2000m;

•The temperature is not higher than +70°C, not lower than -45°C(Over +40°C , use it through capacity reduction, the specific need to negotiate with the manufacturer);

•Atmospheric conditions: such as 90% at 20°C, and taking into account the condensation on the surface due to temperature changes, When the arounding temperature is 40°C, the relative humidity of the atmosphere does not exceed 50%, and a higher relative humidity is allowed at a lower temperature.

•The pollution level is 3;

•Installation category is III;

•Installation magnetic field: The magnetic field of the installation position does not exceed 5 times the earth magnetic field in any direction;

•In a medium without explosion risk, and there is no gas and conductive dust sufficient to corrode metal and destroy insulation in the medium;

•Where there is no snow erosion;

•Installation conditions: It can be installed horizontally or vertically. There should be no significant impact or vibration at the installation place.

•It should not be installed in inflammable and explosive places.

•The circuit breaker has the isolation function, the symbol is
