Ключевые моменты отбора
Типичные применения
Consider CQBD-63 for DC distribution and PV assemblies where the selected voltage, fault-current rating and trip characteristic meet the project design. Non-polar construction does not remove the need to follow the model wiring diagram.

Use these checks to compare the protection function, configuration and related CHAC products before specifying CQBD-63. Related products are selection alternatives or system components, not automatic replacements.
Keep the voltage-to-pole relationship in the purchase order
The CQBD-63 voltage rating rises with the documented pole arrangement.
Use the CQBD-63 curve data for protection checks
The B/C/D letters on this DC model do not carry the same numerical thresholds as a typical AC MCB.
Compare PXB6DC-63M for the required function
The CHAC PXB6DC-63M DC miniature circuit breaker offers overcurrent protection across a 0.5–63A rated-current range. Available in one to four poles, its voltage rating rises from 125V DC for 1P to 500V DC for 4P; use the specified pole arrangement and model-specific tripping characteristics.
Compare CQHD for the required function
The CHAC CQHD PV DC combiner box combines photovoltaic string inputs with DC circuit-breaker protection. Choose from six input/output configurations to match your PV array layout, and confirm the voltage and current ratings for the selected model.
Need Help Specifying CQBD-63?
Отправьте требования к схеме, выбранный вариант конфигурации, целевой рынок и количество для проведения проверки по конкретной модели.
Keep the voltage-to-pole relationship in the purchase order
The CQBD-63 voltage rating rises with the documented pole arrangement. State both the required DC voltage and number of poles when requesting a quotation, and obtain the corresponding connection diagram before panel layout approval.
Use the CQBD-63 curve data for protection checks
The B/C/D letters on this DC model do not carry the same numerical thresholds as a typical AC MCB. Check the published characteristic against load inrush and the minimum fault current, then confirm the ordered current and breaking-capacity variant.

CQBD-63 Product FAQ
Does polarity matter on a DC circuit breaker?
It depends on the breaker design. CQBD-63 is specified as non-polar, but its voltage, pole arrangement and wiring instructions still apply. Do not transfer this characteristic to another DC model without confirmation.
Can a one-pole CQBD-63 be used at 1200V DC?
No. The table assigns 300V DC to 1P and 1200V DC to 4P, with 600V for 2P and 900V for 3P. Use the approved arrangement and wiring for the required voltage.
Are its B, C and D curves the same as AC MCB curves?
No such equivalence should be assumed. CQBD-63 specifies B at 4–7In, C at 8In ±20% and D at 12In ±20%. Use the actual characteristic for protection coordination.
How do I choose the CQBD-63 current rating?
Use circuit design current and conductor ampacity, then check inrush, ambient conditions and the fault-disconnection requirement. Do not increase current rating simply to stop a recurring trip without investigating its cause.
What is the difference between Icu and Ics?
Icu and Ics describe ultimate and service short-circuit interruption duties under stated test conditions. Use the CQBD-63 values for the selected voltage and configuration, and compare them with the prospective fault current.
What should I include in a CQBD-63 purchase specification?
Specify DC operating voltage, poles, rated current, the exact trip characteristic and required fault capacity. Include wiring requirements, load type, destination-market documentation, quantity and any branding request.
Specify the Right CQBD-63 Configuration
Send CHAC your required configuration, application, destination market and estimated quantity. We will review the requested specification and provide the relevant technical documents and commercial proposal.
