DAB6 DC photovoltaic DC circuit breakers
DAB6 DC photovoltaic DC circuit breakers are suitable for circuit with rated current below 125A and rated DC voltage of 1000V. For infrequent conversions. The product has beautiful appearance, standard rail installation, and has on-off display. The terminals have wiring functions up and down. Be sure to pay attention to the polarity of "﹢/﹣" when wiring. It is used for three-pole circuit breakers in 750V circuits, and the balance positive circuit is connected in series with two poles. The circuit breaker can also be equipped with accessories such as auxiliary contacts, alarm contacts and shunt release, which are widely used in communications, batteries, locomotives and other industries.
