CQD5NEZ Product FAQ
Can a DC isolator interrupt a short circuit?
Do not treat CQD5NEZ as an automatic circuit breaker. Its making and short-time withstand ratings support coordination checks; the circuit needs an appropriate fault-clearing protective device.
How do I choose front or side operation?
Use the cabinet layout, door arrangement and access requirements. CQD5NEZ supports both, but dimensions and mechanical operating data differ. Confirm the selected mechanism and shaft arrangement against the actual drawing.
Does an IP65 handle make the entire cabinet IP65?
No. The listed inside/outside-cabinet protection conditions do not certify the complete enclosure. Door cutouts, seals, glands and the assembly construction must also satisfy the required protection level.
Can I choose CQD5NEZ by current rating alone?
No. Check operating voltage, poles, utilization category, switching duty, fault coordination and the installation layout together. Confirm the selected combination in the model-specific documentation before approving a substitute.
Can an isolator be switched under load?
Only within its documented switching duty and voltage/current combination. Confirm the applicable utilization category and instructions for CQD5NEZ; do not assume that every device called an isolator has the same load-break capability.
What information is needed for a CQD5NEZ quotation?
Provide the supply voltage, required current, load duty, pole arrangement, installation drawing and fault-coordination requirements. Add control or auxiliary-contact needs where applicable, plus quantity and destination market.
Specify the Right CQD5NEZ Configuration
Send CHAC your required configuration, application, destination market and estimated quantity. We will review the requested specification and provide the relevant technical documents and commercial proposal.
