CQDF-32 Suport de fusibles DC
El portafusibles de CC CHAC CQDF-32 admite fusibles estándar 10 × 38mm para circuitos fotovoltaicos de CC. Está clasificado para 1000V de CC con una corriente máxima de 32A, y hay disponible una versión con indicador que se adapta al montaje especificado.
Descripción del producto
El CHAC CQDF-32 1000V DC fuse holder accepts 10 × 38mm fuse links for photovoltaic circuits. It has a maximum current rating of 32A and an optional indicator version. The holder and fuse link must be specified together: the base does not determine the required string-fuse current.
Para importadores, distribuidores y fabricantes de equipos, CHAC puede revisar la configuración solicitada en función de los requisitos del circuito y de la documentación del mercado de destino. Acuerde el modelo exacto, los planos y los requisitos de marcado antes de la aprobación de la muestra o de realizar un pedido repetido.
Puntos clave de selección
Aplicaciones típicas
Consider the CQDF-32 for PV string-protection assemblies and combiner boxes. Confirm the selected fuse-link category, DC voltage, interruption rating and permissible power dissipation against the module and circuit design.
Guía de Solicitudes y Selección
| Elemento de selección | CQDF-32 configuration | Qué verificar |
|---|---|---|
| Fuse-link format | 10 × 38mm | Confirm the exact fuse-link series and electrical compatibility, not just its physical fit. |
| Holder ratings | 1000V DC; 32A maximum | Keep the circuit within both ratings and any applicable enclosure-temperature limits. |
| Fuse-current selection | Selected separately for the PV string | Check string current, module maximum series-fuse rating, cable protection and local requirements. |
| Indicator option | With or without indicator | State the required variant on the purchase order and confirm its operating-voltage range. |
Use these checks to compare the protection function, configuration and related CHAC products before specifying CQDF-32. Related products are selection alternatives or system components, not automatic replacements.
Select the fuse before finalizing the holder order
A 32A base does not mean that every PV string needs a 32A fuse.
Plan isolation before fuse replacement
The CQDF-32 data lists DC-PV0.
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 CQDS-32 for the required function
The CHAC CQDS-32 photovoltaic DC isolation switch provides isolation and infrequent switching between PV modules and inverters. Its non-polar design supports selected DC-PV1/DC-PV2 configurations up to 1200V DC and 32A; follow the wiring arrangement specified for the chosen configuration.

Send the circuit requirements, selected configuration, destination market and quantity for a model-specific review.
Select the fuse before finalizing the holder order
A 32A base does not mean that every PV string needs a 32A fuse. Start with the module data and string design, then confirm a suitable PV fuse link and its compatibility with the CQDF-32. Include the fuse-link part number in the approved assembly specification.
Plan isolation before fuse replacement
The CQDF-32 data lists DC-PV0. Do not treat the holder as a load-break disconnect or open it under load. Establish a suitable isolation procedure and verify the electrical condition before servicing a fuse; an indicator does not prove absence of voltage.
How to Specify a CQDF-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.

CQDF-32 Product FAQ
What fuse fits a CQDF-32 holder?
The holder accepts the specified 10 × 38mm format. Confirm the exact PV fuse-link series, voltage, current, interruption rating and permitted power dissipation before approving the combination. Physical size alone is not sufficient.
Does a 32A fuse holder require a 32A fuse?
No. The 32A value is the maximum holder current. The selected fuse current depends on the string design, module maximum series-fuse limit, cable protection and installation conditions, and must remain within the holder rating.
Can I open a solar fuse holder under load?
Do not use the CQDF-32 as a load-break switch. Its stated utilization category is DC-PV0. Follow the approved isolation procedure before opening the holder, and use a suitable DC switching device where load disconnection is needed.
Can a fuse holder protect a circuit without a fuse link?
No. The holder supports and connects the fuse link; the correctly selected link provides the specified overcurrent interruption. Define both items in the assembly bill of materials.
Can a 1000V DC fuse holder be used at 1500V DC?
No. Do not exceed the CQDF-32 1000V DC operating rating. Select a holder and fuse link documented for the actual maximum circuit voltage.
What should a CQDF-32 quotation include?
Specify the exact compatible fuse-link type and current, DC operating voltage, indicator requirement, quantity and destination market. Confirm whether the quotation includes holders only or a holder-and-fuse combination.
Specify the Right CQDF-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.
