First, the scope

DZ47Z-63 series photovoltaic DC miniature circuit breaker applies to the rated current of 63 or less, DC rated voltage 125V, 220V, 440V line, the DC transmission and distribution systems for facilities and electrical equipment overload , infrequent conversion of short-circuit protection and the link with. Product appearance, standard rail mounting, with a show-off. Terminals and down all wiring function, wiring must pay attention to "+/-" polarity for 440V three-pole circuit breakers, the balance is positive circuit diode connected in series. The circuit breaker can also be installed auxiliary contacts, alarm contacts shunt release and other accessories, it is widely used in communications, batteries, locomotives and other industries.
Small DC circuit breaker in line with IEC60947-2-1997, GB14048.2-200.1 standard & nbsp;

Second, model and specification

Third, the working conditions

◇ installation site altitude less than 2000m;
◇ ambient air temperature is not higher than the positive negative forty degrees Celsius is not less than five degrees Celsius; and an average daily temperature of not more than thirty-five degrees positive (except special orders)
◇ installation location relative humidity. The maximum temperature does not exceed fifty percent positive forty degrees Celsius, at a lower temperature allows a higher relative humidity, for example twenty degrees Celsius over 90 percent. Condensation temperature change from the dry to produce the occasional special measures should be taken.
◇ in the air no danger of explosion of media and not enough to corrode metal and damage the insulation of gas and conductive dust areas.
◇ no rain and snow.
◇ Pollution level III.
◇ Installation Category: Installation category for the main circuit breaker Ⅲ, not connected to the auxiliary circuits and control circuits for the main circuit installation category Ⅱ.

Fourth, the structural features

DZ47Z-63 DC miniature circuit breaker is a new product in the MCB, based on research and development. Using magnetic blow interrupter characteristic arcing time is short, high breaking capacity, reliable performance. & Nbsp;
