CQW2 Product FAQ
Where is the CQW2 ACB used?
It is intended for large low-voltage distribution positions such as incomers, bus couplers or feeders when the selected frame, controller and installation arrangement are suitable.
How do I choose the frame and current?
Use design current, service conditions, short-circuit study, selectivity, poles, mounting type and controller functions. Frame size alone is not sufficient.
What is Icu?
Icu is the rated ultimate short-circuit breaking capacity under the applicable product standard. Confirm the test voltage and exact variant before using the value in a design.
Fixed or drawout mounting?
Choose from the installation and maintenance strategy, required isolation and switchboard design. Verify the matching cradle and interlocks.
What controller options are available?
The CQW2 record identifies standard, electronic and communication controller options. Confirm protection functions and control voltage for the order.
How should an ACB be commissioned?
Test insulation, primary and secondary circuits, trip functions, interlocks, racking positions and coordination settings with qualified personnel.
Confirm the Right CQW2 Configuration
Send the exact model, operating conditions, quantity, destination market and required documents. CHAC will review the request against the published product data.
