Przełączniki DC z serii CQB7DC-63
The CQB7DC-63 Zostaje ona określona dla ochrony przed przeciążeniem i zwarciem stałym. Wybierz ją w oparciu o opublikowane dane dotyczące napięcia, prądu, biegunów oraz zabezpieczeń, a następnie potwierdź koordynację przewodów, warunki awarii, wymagania dotyczące obudowy oraz lokalne zasady instalacji.
Product Overview
CQB7DC-63 is a 1000V DC circuit breaker for DC voltage and pole limits vary by model table applications. It is intended for PV, telecom, energy-storage or control circuits when the DC fault study supports the rating; this describes an evaluation context, not a universal approval. Confirm the complete circuit design before specifying the product.
DC overload and short-circuit protection is distinct from adjacent protection functions. Do not infer AC/DC suitability, residual-current protection, automatic control or isolation performance from the product family name alone.
Key Features
Typical Applications
PV, telecom, energy-storage or control circuits when the DC fault study supports the rating. Verify system voltage, expected fault current or leakage, wiring arrangement, environment, coordination and applicable rules for the ordered configuration.

CQB7DC-63 Product FAQ
What is the CQB7DC-63 used for?
The CQB7DC-63 is specified for DC overload and short-circuit protection in DC voltage and pole limits vary by model table applications, within the ratings and configurations listed in its technical table. Final suitability depends on the complete circuit design.
How does the CQB7DC-63 work?
Its operating principle follows the documented function: DC overload and short-circuit protection. Use the exact model documentation for thresholds, timing, trip behaviour, terminals and test procedures.
How do I choose the CQB7DC-63 rating and poles?
Start with the design current and system arrangement, then choose only a published option. The page lists pole options as 1P / 2P / 3P / 4P as listed; confirm neutral, polarity, conductors and isolation requirements.
What safety limitation applies to the CQB7DC-63?
Do not treat the CQB7DC-63 as a universal substitute for another device. Confirm Use the exact model's DC interruption data, the system voltage, fault or leakage conditions and any separate upstream protection before selection.
Can the CQB7DC-63 be used in another circuit type?
Only when the exact ordered configuration is rated for that circuit. AC and DC duties, residual-current devices, isolators, smart controls and voltage protectors are not interchangeable by appearance or current rating.
How should the CQB7DC-63 be installed and tested?
Use the exact product drawing, terminal identification and instructions. A qualified person should verify isolation, conductors, torque, settings, coordination and functional tests before energising the circuit.
