CDQ3HB Automatic Transfer Switch (ATS) – Integrated Overload & Short Circuit Protection | 4 Pole | 100A–630A | 25kA–50kA ICU
The Delixi CDQ3HB Automatic Transfer Switch (ATS) is an industrial-grade intelligent power switching solution designed to provide automatic source transfer combined with built-in overload and short circuit protection, delivering enhanced operational safety and system reliability.
Unlike conventional ATS systems that only perform source switching, the CDQ3HB Series integrates protection functionality directly into the transfer switch, minimizing installation complexity while improving electrical system protection.
The ATS automatically transfers electrical loads between utility power and backup sources during outages or abnormal conditions, ensuring uninterrupted power continuity for critical applications.
Integrated protection capabilities include:
-
Overload protection
-
Short circuit protection
-
Automatic source switching
-
Enhanced fault interruption capability
Designed for industrial and commercial environments requiring dependable power continuity, the CDQ3HB series combines transfer switching and protective functionality within a single integrated solution.
Supporting current ratings from 100A to 630A and breaking capacities up to 50kA ICU, this ATS is engineered for demanding power distribution applications.
Manufactured according to IEC 60947-6-1 international standards, the Delixi CDQ3HB delivers industrial-grade reliability and advanced protection capability.
