CQDS-32 Interruttore di isolamento DC fotovoltaico
L'interruttore di isolamento DC fotovoltaico CHAC CQDS-32 fornisce l'isolamento e la commutazione poco frequente tra i moduli PV e gli inverter. Il suo design non polarizzato supporta configurazioni DC-PV1/DC-PV2 selezionate fino a 1200V DC e 32A; seguire la disposizione dei cablaggi specificata per la configurazione scelta.
Riassunto del prodotto
Il CHAC CQDS-32 photovoltaic DC isolation switch provides a disconnection point between PV modules and the inverter. Its non-polar design, lockable handle and DC-PV1/DC-PV2 options support selection for the actual string arrangement rather than voltage alone.
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 CQDS-32 in a protected PV assembly where the design requires DC isolation and infrequent switching. The IP20 device needs a suitable enclosure; it is not a weatherproof rooftop disconnect by itself.
Modulazioni e Guida alla selezione
| Elemento selezionabile | CQDS-32 configuration | Cosa verificare |
|---|---|---|
| Operating duty | DC-PV1 / DC-PV2 | Match the switching duty to the PV string arrangement and possible reverse current. |
| Voltage and current | Up to 1200V DC / 32A, configuration dependent | Confirm the paired voltage/current rating and wiring diagram; do not combine independent maximum values. |
| Connections | Four-pole configurations with designated connection diagrams | Use the specified terminal bridges and conductor arrangement, not a layout inferred from the number of poles. |
| Installazione | IP20; vertical or horizontal installation | Confirm enclosure protection, access to the handle and cable bending space. |
Use these checks to compare the protection function, configuration and related CHAC products before specifying CQDS-32. Related products are selection alternatives or system components, not automatic replacements.
Choose the switching duty for the PV array
Parallel strings can introduce reverse-current conditions that a simple voltage check misses.
Use the wiring diagram for the ordered configuration
A non-polar design does not make every series connection acceptable.
Compare CQHS for the required function
The CHAC CQHS PV DC combiner box combines photovoltaic string inputs with a DC isolator for DC-side disconnection. Choose from six input/output configurations to match your PV array layout, and confirm the voltage and current ratings for the selected model.
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.
Need Help Specifying CQDS-32?
Send the circuit requirements, selected configuration, destination market and quantity for a model-specific review.
Choose the switching duty for the PV array
Parallel strings can introduce reverse-current conditions that a simple voltage check misses. Provide the string arrangement, maximum open-circuit voltage at the lowest design temperature and design current. CHAC can then confirm the applicable CQDS-32 configuration and utilization category.
Use the wiring diagram for the ordered configuration
A non-polar design does not make every series connection acceptable. Match the terminal arrangement to the approved drawing and check that all required live conductors are isolated. The switch does not replace the array overcurrent-protection design.
How to Specify a CQDS-32 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.

CQDS-32 Product FAQ
Can a DC isolator switch replace a circuit breaker?
No. The CQDS-32 provides switching and isolation, not an automatic overload or short-circuit trip function. Specify the required fuse or circuit breaker separately and coordinate it with the PV circuit.
What is the difference between DC-PV1 and DC-PV2?
They identify different PV switching duties, including different reverse-current conditions. Select the category using the array arrangement and manufacturer ratings. The CQDS-32 lists both categories, but the applicable voltage, current and wiring combination must be confirmed.
Can CQDS-32 be installed outdoors without a box?
The device is IP20, so it should not be exposed as a standalone outdoor switch. Select an enclosure, glands and installation position suitable for the site and preserve the required operating access.
Can I choose CQDS-32 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 CQDS-32; do not assume that every device called an isolator has the same load-break capability.
What information is needed for a CQDS-32 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 CQDS-32 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.
