Puntos clave de selección
Aplicaciones típicas
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.

Need Help Specifying CQBD-63?
Send the circuit requirements, selected configuration, destination market and quantity for a model-specific review.
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.
How to Specify a CQBD-63 Order
Use the configuration details below in the purchase specification. Keep the approved drawing revision and product identification with the order so repeat deliveries can be checked consistently.

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.
