Direct answer
Solar branch connectors combine matched PV string or module outputs in small configurations. They are useful in limited cases but do not replace a protected combiner box when fuses, SPD or isolation are required.
Branch connector RFQs should include current, voltage and string layout so the part is not used as a shortcut for a combiner box.

FAQ
Can a branch connector replace a combiner box?
Only in limited small layouts. If the design needs fuses, SPD, isolator or monitoring, use a combiner box.
What information is needed for a branch connector quote?
Send the string layout, voltage, current, cable size and connector mating requirement.
