Integrated Air Circuit Breaker YCW9X-1600

YCW9X-1600 integrated circuit breaker is one of the new circuit breakers developed using advanced technology. This product is suitable for general distribution systems, new energy distribution systems, multi-energy distribution networks, inverters and distributed power rotation. It has isolation function, small size, high breaking capacity and other multi-functional features for grid-connected operation and protection of motor power supplies.

Standards: IEC60947-1 ,IEC60947-2

Operating conditions

The ambient air temperature is -5 °C ~ +40 °C(beyond the range can be reduced capacity use), and the average value of 24h does not exceed +35°C ;

The elevation of the installation site does not exceed 2000m, more than 2000m capacity reduction use;

The relative humidity of the air at the installation site does not exceed 50% when the maximum temperature is +40°C , and can have a higher relative humidity at lower temperatures,such as 90% at 20°C .Special measures should be taken for condensation occasionally caused by temperature changes;Pollution level is level 3;Circuit breaker main circuit installation category IV, the rest of the auxiliary circuit and control circuit installation category III;

The circuit breaker should be installed in a place where there is no explosion risk, no conductive dust,no rain and snow attack, and no enough to corrode metal and destroy insulation.
