It is designed exclusively for direct current (DC), unlike conventional AC circuit breakers that are not suitable for such applications. Its compact DIN rail format makes it suitable for any residential or industrial photovoltaic electrical panel.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-benefits\"\u003e\n\n\u003ch2\u003eWhat you get with this product\u003c\/h2\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eReal protection for solar panels and inverter — automatically intervenes in case of short circuit or overload, limiting material damage\u003c\/li\u003e\n\n\u003cli\u003eNatively supported 1000V DC voltage — designed for photovoltaic circuits, not an adaptation of an AC circuit breaker\u003c\/li\u003e\n\n\u003cli\u003eBipolar (2 poles) — simultaneously interrupts both conductors of the DC circuit, in accordance with good safety practices in solar installations\u003c\/li\u003e\n\n\u003cli\u003eQuick mounting on 35mm DIN rail — mounts in the electrical panel in minutes, without special tools\u003c\/li\u003e\n\n\u003cli\u003eBreaking capacity 10000A — handles short circuit currents found in medium and large photovoltaic installations\u003c\/li\u003e\n\n\u003cli\u003eRobust DALBI NTS-63 construction — resistant to vibrations, varying temperatures, and prolonged use in demanding technical environments\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-how\"\u003e\n\n\u003ch2\u003eHow it works and how to install it\u003c\/h2\u003e\n\n\u003cp\u003eThe bipolar DC MCB is mounted on a 35mm DIN rail in the photovoltaic distribution board, on the direct current branch between the solar panels and the inverter. The thermomagnetic mechanism reacts to prolonged overload (thermal protection) and instantaneous short circuit (magnetic protection), automatically disconnecting the circuit on both poles simultaneously. Reconnection is done manually, after identifying and remedying the cause, by simply operating the handle.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003cdiv class=\"cl-faq\"\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use a regular AC MCB instead for solar panels?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eNo. Standard AC circuit breakers are not approved for direct current and cannot safely extinguish a DC arc, which creates a fire hazard.
