PXB6HDC-125M DC Miniature Circuit Breaker
Itu PXB6HDC-125M Direkomendasikan untuk perlindungan overload DC dan arus pendek. Pilihannya berdasarkan tegangan, arus, kutub, dan data perlindungan yang tercantum, kemudian konfirmasi koordinasi kabel, kondisi kerusakan, persyaratan penutup, dan aturan pemasangan lokal.
Gambaran Produk
PXB6HDC-125M is a high voltage DC circuit breaker for 1P DC 250V; 2P DC 500V; 3P DC 750V; 4P DC 1000V 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.

PXB6HDC-125M Product FAQ
What is the PXB6HDC-125M used for?
The PXB6HDC-125M is specified for DC overload and short-circuit protection in 1P DC 250V; 2P DC 500V; 3P DC 750V; 4P DC 1000V applications, within the ratings and configurations listed in its technical table. Final suitability depends on the complete circuit design.
How does the PXB6HDC-125M 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 PXB6HDC-125M 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; confirm neutral, polarity, conductors and isolation requirements.
What safety limitation applies to the PXB6HDC-125M?
Do not treat the PXB6HDC-125M as a universal substitute for another device. Confirm 6kA Icu; 6kA Ics, the system voltage, fault or leakage conditions and any separate upstream protection before selection.
Can the PXB6HDC-125M 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 PXB6HDC-125M 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.
Confirm the Right PXB6HDC-125M Configuration
Send the model, rating, poles, system voltage, application, quantity and document requirements. CHAC will review the request against the published data.
