CQV2 Product FAQ
What protection does the CQV2 provide?
The product record describes overload, phase-failure and short-circuit protection for compatible AC motor circuits. Confirm the exact setting range and motor data.
How is the current setting selected?
Set the protector from the motor nameplate and measured operating conditions, then verify starting current, ambient temperature and conductor coordination.
Can it be used as an isolator?
The current record identifies an isolation function, but the installation must still meet the required isolation, enclosure and local-code conditions.
Which motors are suitable?
The published application is three-phase squirrel-cage asynchronous motors. Confirm motor power, voltage, duty and starting method.
What accessories can be added?
Auxiliary, signal or under-voltage accessories depend on the CQV2 variant. Check the exact accessory code and wiring diagram.
How should nuisance trips be investigated?
Record motor current, phase balance, start time, ambient temperature and terminal condition before changing the setting.
