Dispositivo di protezione da sovratensione della serie CQ-T2-DC (SPD)
Il Dispositivo di protezione da sovratensione della serie CQ-T2-DC (SPD) is a CHAC surge protection device for transient overvoltage protection. The page keeps the model-specific technical table and original product images so buyers can verify voltage, current, configuration, mounting and applicable standards before ordering. Final suitability depends on the complete circuit, installation method and destination-market rules.
Product Overview
CQ-T2-DC Series Surge Protection Device (SPD) is a surge protection device intended for transient overvoltage protection. The current product record identifies it for PV, building distribution and control panels. Use the exact model variant and preserved technical source as the basis for procurement rather than assuming that every family member has the same rating.
Verified source summary: The technical table below is the controlling source for model-specific values.
Key Features
Typical Applications
Typical use can include PV, building distribution and control panels when the project confirms system voltage, current, fault or surge exposure, conductor and enclosure requirements, and the selected variant’s installation instructions. This page does not replace the project design or the authority having jurisdiction.
Applications and Selection Guide
Use the following decision points with the preserved model data. Product-family descriptions explain intent, but the exact technical table controls the ordered variant.
| Selection point | Dispositivo di protezione da sovratensione della serie CQ-T2-DC (SPD) | What the project must confirm |
|---|---|---|
| Applicazione | SPD projects | Confirm the actual system and environment |
| Selection basis | transient overvoltage protection | Use the exact model and technical table |
| Installation | Follow the model instructions | Check mounting, clearances and termination |
| Compliance | Use the listed standard where applicable | Verify edition, scope and destination rules |
| Adjacent product | Evaluate the related CHAC family where function differs | Do not substitute without engineering review |

CQ-T2-DC Product FAQ
What does the CQ-T2-DC SPD protect?
It is intended to limit transient overvoltage in the system stated by the product record. Confirm the AC or DC system, protection zone, discharge rating and backup protection for the selected variant.
How do I choose an SPD discharge rating?
Use the project's lightning and transient exposure, system arrangement and the device's published In, Imax or Iimp values. Do not select by nominal voltage alone.
Does an SPD replace a circuit breaker?
No. An SPD diverts transient energy, while a breaker or fuse provides overcurrent protection. The two devices must be coordinated.
What should be checked before installation?
Check voltage, wiring mode, earthing, backup fuse, lead length, enclosure and the manufacturer's connection diagram.
When should the module be replaced?
Use the status indicator and the product instructions. Investigate the cause of a fault indication before fitting a replacement module.
What documents can CHAC provide?
Request the applicable datasheet, wiring diagram, dimensions and verified compliance documents for the ordered configuration.
Confirm the Right CQ-T2-DC Configuration
Send the exact model, operating conditions, quantity, destination market and required documents. CHAC will review the request against the published product data.
