CQAU2 Product FAQ
How does the CQAU2 work?
The CQAU2 monitors the supply against its published window: normal 175–255V; overvoltage trip ≥265±10V; undervoltage trip ≤165±10V. When the relevant limit is reached, the compatible breaker accessory function responds as specified by the product design.
What is an over/under-voltage protection device?
It monitors supply voltage and operates when voltage moves outside defined limits. The correct thresholds and reset behavior must be taken from the selected model's documentation.
What voltage range is published for the CQAU2?
The published reference is 230V AC 50Hz; Ui 415V and normal 175–255V; overvoltage trip ≥265±10V; undervoltage trip ≤165±10V. Confirm the system voltage, tolerance and installation conditions before ordering.
Is the CQAU2 the same as a shunt trip release?
No. A voltage release responds to its monitored voltage window, while a shunt trip is controlled by a separate energizing signal. Select the function that matches the protection or control logic.
Which breaker is compatible with the CQAU2?
The CQAU2 is an accessory for a compatible breaker interface. Confirm the exact breaker family, mounting position and coordination requirements.
What should be checked during installation of the CQAU2?
Check voltage, thresholds, wiring, breaker interface, enclosure conditions and the manufacturer's installation instructions. Testing must be performed by qualified personnel.
