Breaker Case Molded Case Series CQM7DC
Itu CQM7DC MCCB menyediakan perlindungan terhadap beban lebih dan arus pendek untuk sistem DC dalam rentang 63–1600A yang telah diterbitkan. Spesifikasi harus mengikuti tegangan sistem, beban, koordinasi konduktor, arus gangguan potensial, dan peraturan yang berlaku—bukan hanya nilai ampere saja.
Gambaran Produk
CQM7DC adalah MCCB arus searah untuk aplikasi distribusi dan proteksi DC 1500V. Rentang produk yang dipublikasikan mencakup 63–1600A dengan opsi 2P / 3P / 4P. Pemilihan tergantung pada desain sistem tenaga secara keseluruhan, termasuk tingkat gangguan, koordinasi, kapasitas hantar arus konduktor, kondisi kabinet, serta peraturan setempat.
The saved model record lists UL 489 requirements listed on the page as the applicable standard reference. No certification claim is added beyond the model record.
Fitur Utama
Aplikasi Biasa
Typical applications include solar PV, EV charging and energy-storage distribution where the complete DC fault study supports the rating. These are evaluation contexts rather than universal approvals. Confirm the exact frame, voltage, breaking duty, trip unit, accessories and installation method before specification.

CQM7DC Product FAQ
What is the CQM7DC MCCB used for?
The CQM7DC is specified for overload and short-circuit protection for DC systems in 1500V DC systems within the published 63–1600A range. Suitability depends on the fault study, conductor coordination, enclosure and local rules.
What is the CQM7DC 1500V DC rating?
The page lists 1500V DC as the rated operational voltage. DC interruption is not interchangeable with AC interruption, so the pole arrangement, arc path, fault current and installation instructions must be checked for the actual PV, EV or storage circuit.
How do I choose the CQM7DC rated current and poles?
Start with the design current and conductor calculation, then choose a published current within 63–1600A and poles from 2P / 3P / 4P. Neutral treatment, fault level, ambient conditions and coordination also need review.
What breaking capacity should I check on the CQM7DC?
Use the declared Icu/Ics values vary by voltage and frame; verify the ordered table for the exact frame, voltage and configuration. The prospective short-circuit current at the installation point must be within the applicable duty; a larger ampere value alone is not a selection rule.
Can the CQM7DC replace an MCB or an earth-leakage device?
An MCCB is not automatically a like-for-like replacement. The CQM7DC provides overload and short-circuit protection for DC systems; residual-current protection, DC interruption, adjustable settings and other functions must be confirmed separately from the project requirement.
How should the CQM7DC be installed and tested?
Use only the exact model drawing, terminal identification and accessory instructions. A qualified person should verify isolation, conductor size, torque, clearances, settings, fault duty and functional tests before energising the circuit.
Confirm the Right CQM7DC Configuration
Send the frame, rated current, poles, protection function, system voltage, expected fault level, destination market and quantity. CHAC will review the request against the published model range.
