The DALBI NTS-63 model is specifically built for the high direct current voltage found in solar systems, where classic AC fuses do not provide adequate protection. Its compact DIN rail format makes it compatible with any standard photovoltaic 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 1000V DC protection — specifically calibrated for direct current, not an adaptation from AC, which means reliable tripping under solar system conditions\u003c\/li\u003e\n\n\u003cli\u003eFast shutdown in case of short circuit or overload — limits the risk of fire and protects the inverter and wiring from irreversible damage\u003c\/li\u003e\n\n\u003cli\u003eConvenient manual disconnection — the two independent levers allow circuit isolation for maintenance interventions without additional tools\u003c\/li\u003e\n\n\u003cli\u003eDirect installation on 35mm DIN rail — mounts in any standard photovoltaic panel in minutes, without modifying the panel's structure\u003c\/li\u003e\n\n\u003cli\u003eRobust construction for harsh environments — resistant to temperature and humidity variations specific to solar installations mounted outdoors or in unheated technical spaces\u003c\/li\u003e\n\n\u003cli\u003eBipolar 2P format — simultaneously interrupts both poles of the DC circuit, complying with safety requirements for photovoltaic installations\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 DC 1000V MCB is mounted on the 35mm DIN rail of the photovoltaic panel by simply sliding it into place, without additional screws for rail fixation. Input and output cables are connected to the screw terminals at the top and bottom of the device. Upon detecting a short circuit current or overload, the internal mechanism automatically trips both levers, interrupting the DC circuit; resetting is done manually after the cause is remedied.\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 of this one?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eNo. AC fuses are not designed to extinguish the electric arc at high direct current voltage — an AC fuse mounted on a 1000V DC circuit will not trip correctly and can cause fire or equipment destruction.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat nominal current should I choose for my solar installation?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe nominal current of the fuse should be equal to or slightly higher than the maximum current of the photovoltaic panel string (Isc of the string).
