This DC circuit breaker is designed to protect the cables located between each string of photovoltaic modules and the photovoltaic inverter against overloads and short DC circuits (see application diagram).\u003c\/p\u003e\u003c!-- details --\u003e\n\u003cp data-mce-fragment=\"1\"\u003eCombined with a switch, the JB will be installed in a string PV protection enclosure at the end of each string of photovoltaic modules.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eDC circuit can be locked (by a padlocking device) in the OFF position as a safety measure for the removal of the PV inverter. Since a fault current can flow in the reverse direction to the operating current, the JB can detect and protect against any bidirectional current. To ensure the safety of the installation, it is necessary, depending on the various types of application, to combine the JB with:\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eA residual current device at the AC end,\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eA fault passage detector (insulation monitoring device) at the DC end\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAn earth protection circuit breaker at the DC end\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-mce-fragment=\"1\"\u003eIn all cases, fast action on site will be required to clear the fault (protection not ensured in the event of a double fault).\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eJB is not polarity sensitive: (+) and (-) wires can be inverted without any risk.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eDC Circuits Breaker is: Delivered with three inter-pole barriers to providing increased isolation distance between two adjacent connectors.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe miniature circuit breakers for DC circuit are equipped with a special magnet, which is able to force the arc to the arc chute and extinguish the arc into a very short time.
