1, introduction
DW17 series air circuit breaker is applicable to the exchange of 50Hz 380V, 660V or 440V DC voltage, current to 3900A power distribution network, to the distribution of power and protection of power lines and equipment overload, under-voltage, short circuit, under normal conditions, can be used as a line is not frequent conversion of. Following the 1250A circuit breaker in 50Hz AC voltage 380V network can be used in protection of motor overload and short circuit. In normal conditions can also be as infrequent start of motor.

3, the use of conditions
Delta elevation not exceeding 2000m; the maximum inclination of 22.5 degrees;
A surrounding medium temperature not higher than + 40 degree C ( for marine products of + 45 degrees C ) and less than - 5 degrees C;
It can tolerate humid air, salt fog, mist, mold, the effects of nuclear radiation;
It was the ships normal vibration can work reliably under seismic conditions; ( 4G ) can reliably work;
Being without the risk of explosion in the medium, and medium non-metal corrosion and damage to the insulation of gas and dust where conductive;
Delta in the absence of snow or rain.
