CQM7DC MCCB Selection Summary<\/h2>\n

The CQM7DC is specified for overload and short-circuit protection for DC systems in 1500V DC systems. Published options include 63\u20131600A, 2P \/ 3P \/ 4P and 5In or 10In instantaneous setting. The applicable fault duty is Icu\/Ics values vary by voltage and frame; verify the ordered table. Confirm the ordered frame, protection function, conductors, installation conditions and local rules before use.<\/p>\n
