PXB6DC-63M Brettina di cortocircuito a circuito stampato
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.
Riassunto del prodotto
Il CHAC PXB6DC-63M DC miniature circuit breaker offers rated currents from 0.5A to 63A for DC overcurrent protection. Its four-pole configuration is rated at 500V DC; the one-, two- and three-pole versions have lower operating-voltage ratings.
Per importatori, distributori e produttori di apparecchiature, CHAC può verificare la configurazione richiesta rispetto ai requisiti del circuito e alla documentazione del mercato di destinazione. Concordare il modello esatto, i disegni e i requisiti di marcatura prima dell’approvazione del campione o di un ordine ripetuto.
Punti chiave di selezione
Applicazioni tipiche
Use the PXB6DC-63M in DC control or distribution assemblies where the selected current, poles and operating voltage match the circuit. The low-current choices can be relevant to smaller branches, but the actual load and conductor design determine the rating.
Modulazioni e Guida alla selezione
| Elemento selezionabile | PXB6DC-63M configuration | Cosa verificare |
|---|---|---|
| Voltage by pole count | 1P 125V; 2P 250V; 3P 375V; 4P 500V DC | Do not treat 500V as the rating of every version. |
| Rated-current choices | 0.5–63A in the published steps | Choose from the actual available ratings rather than treating the range as continuously adjustable. |
| Interruzione di guasto | Icu 10kA; Ics 7.5kA | Check both values and their stated test conditions against the project fault level. |
| Termination | Up to 25mm²; terminal torque 2.5N·m | Verify conductor preparation and terminal instructions for the ordered device. |
Use these checks to compare the protection function, configuration and related CHAC products before specifying PXB6DC-63M. Related products are selection alternatives or system components, not automatic replacements.
Order the exact current step and DC characteristic
The range includes fractional-ampere choices as well as common distribution ratings.
Check terminal fit before approving the panel
The stated terminal capacity does not set the permissible circuit current by itself.
Compare CQBD-63 for the required function
The CHAC CQBD-63 DC circuit breaker offers overload and short-circuit protection with a non-polar design and contact-position indication. One- to four-pole versions cover DC voltages from 300V to 1200V; match the pole arrangement and tripping characteristic to the circuit.
Compare CQM5NEZ for the required function
Il disgiuntore a custodia stampata CHAC CQM5NEZ DC è disponibile con unità di arresto magnetiche o termomagnetiche per circuiti DC da 1500 V. Se sono richieste sia la protezione da sovraccarico che quella da cortocircuito, selezionare la versione termomagnetiche. Le versioni da 350 A e 630 A coprono i valori di corrente da 63 A a 630 A, con una capacità di arresto determinata dalla versione del quadro e dalla versione M/H.
Need Help Specifying PXB6DC-63M?
Invia i requisiti del circuito, la configurazione selezionata, il mercato di destinazione e la quantità per una verifica specifica del modello.
Order the exact current step and DC characteristic
The range includes fractional-ampere choices as well as common distribution ratings. Provide the load profile and the required current step. The technical characteristics use 4In/8In/12In references; do not relabel them as standard AC B/C/D curves.
Check terminal fit before approving the panel
The stated terminal capacity does not set the permissible circuit current by itself. Coordinate cable ampacity, bending space, termination method and the specified tightening torque. Obtain the selected configuration drawing rather than copying the wiring from another DC breaker.

PXB6DC-63M Product FAQ
Can an AC breaker replace a PXB6DC-63M?
Not without documented suitability for the DC circuit. Arc interruption, operating voltage and pole connections must be verified for DC service. Select the correctly rated PXB6DC-63M configuration or another documented DC device.
Which PXB6DC-63M version is rated for 500V DC?
The published 500V DC rating applies to the 4P version. The listed ratings are 125V for 1P, 250V for 2P and 375V for 3P. Confirm the corresponding wiring diagram.
Is the 63A model the only available current rating?
No. The series includes 0.5, 1, 1.6, 2, 2.5, 3, 4, 5, 6, 8, 10, 13, 16, 20, 25, 32, 40, 50 and 63A. Select the required step from the circuit and conductor design.
How do I choose the PXB6DC-63M 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 PXB6DC-63M values for the selected voltage and configuration, and compare them with the prospective fault current.
What should I include in a PXB6DC-63M 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 PXB6DC-63M 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.
