Interruttore di isolamento del telaio DC della serie CQW5NEDZ
L'interruttore di isolamento in corrente continua CHAC CQW5NEDZ consente la commutazione e l'isolamento dei circuiti principali fotovoltaici e di accumulo energetico. Tre dimensioni del telaio coprono correnti nominali da 400A a 4000A a 1500V in corrente continua; selezionare il telaio e la categoria di utilizzo in base all'applicazione.
Riassunto del prodotto
Il CHAC CQW5NEDZ DC frame isolation switch serves higher-current DC main-circuit applications. Its 1600A, 2500A and 4000A frames operate at 1500V DC, with frame-specific utilization categories and short-time withstand 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
Evaluate CQW5NEDZ for PV and energy-storage DC main circuits requiring switching and isolation. Coordinate the complete assembly with its fault-protection design, control supplies and installation conditions; an isolation switch is not an automatic overcurrent breaker.
Modulazioni e Guida alla selezione
| Elemento selezionabile | CQW5NEDZ configuration | Cosa verificare |
|---|---|---|
| Fotogramma e corrente | 1600 / 2500 / 4000A frames; listed currents across 400–4000A | Use the available current steps for the selected frame. |
| Voltage and poles | 1500V DC; 2P | Confirm the layout and connection arrangement. |
| Utilization category | 1600: DC-22A / DC-PV2; 2500/4000: DC-23A / DC-PV2 | Do not transfer one frame’s switching duty to another. |
| One-second withstand | 1600: 50kA; 2500: 85kA; 4000: 100kA | Keep the frame and duration with the current rating when coordinating protection. |

Send the circuit requirements, selected configuration, destination market and quantity for a model-specific review.
Match the frame to switching and fault-withstand duty
The three frames differ in more than current. Compare utilization category, short-time withstand duty, dimensions and connection spacing. The 100kA/1s value belongs to the 4000 frame and must not be generalized across the range.
Define the control supplies before cabinet wiring
State the voltages for the motor mechanism, closing and release functions and the required signaling. Where control voltages differ, follow the separate-supply requirements in the approved drawing. Confirm the ready-to-close and interlock logic before commissioning.

CQW5NEDZ Product FAQ
What is the difference between Icw and breaking capacity?
Icw describes short-time withstand duty for a stated duration; it does not describe automatic fault interruption. CQW5NEDZ is a DC frame isolation switch, so the fault-clearing device and coordination must be specified separately.
Does every CQW5NEDZ frame have a 100kA rating?
No. The one-second withstand values are 50kA for the 1600 frame, 85kA for the 2500 frame and 100kA for the 4000 frame. Use the exact frame and duration in the design review.
Can all operating accessories share one control supply?
Only when the selected accessory voltages and circuit design permit it. The product instructions require appropriate separate supplies if the control voltages differ. Confirm the motor, closing and release requirements against the exact wiring diagram.
Can I choose CQW5NEDZ by current rating alone?
No. Check operating voltage, poles, utilization category, switching duty, fault coordination and the installation layout together. Confirm the selected combination in the model-specific documentation before approving a substitute.
Can an isolator be switched under load?
Only within its documented switching duty and voltage/current combination. Confirm the applicable utilization category and instructions for CQW5NEDZ; do not assume that every device called an isolator has the same load-break capability.
What information is needed for a CQW5NEDZ quotation?
Provide the supply voltage, required current, load duty, pole arrangement, installation drawing and fault-coordination requirements. Add control or auxiliary-contact needs where applicable, plus quantity and destination market.
Specify the Right CQW5NEDZ 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.
