Installation is done by simply attaching it to the DIN rail in the solar electrical panel, followed by connecting the DC cables to the input and output terminals — an operation accessible to any authorized electrician. After remedying the cause, the circuit breaker is manually reset by operating the lever.\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 for solar panels?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eNo. Standard AC MCBs are designed for alternating current and cannot extinguish the electrical arc generated by direct current at high voltages, which presents a major fire risk.
