Bagi para importir, distributor, dan produsen peralatan, CHAC dapat meninjau konfigurasi yang diminta sesuai dengan persyaratan sirkuit serta dokumen pasar tujuan. Pastikan kesepakatan mengenai model yang tepat, gambar teknis, dan persyaratan penandaan sebelum persetujuan sampel atau pemesanan ulang.
Poin-Poin Pilihan Utama
Aplikasi Biasa
Evaluate CQW5NEDZ for PV and energy-storage DC main circuits requiring switching and isolation. Coordinate the complete assembly with its fault-protection design, control supplies and installation conditions; an isolation switch is not an automatic overcurrent breaker.

Use these checks to compare the protection function, configuration and related CHAC products before specifying CQW5NEDZ. Related products are selection alternatives or system components, not automatic replacements.
Match the frame to switching and fault-withstand duty
The three frames differ in more than current.
Define the control supplies before cabinet wiring
State the voltages for the motor mechanism, closing and release functions and the required signaling.
Compare CQD5NEZ for the required function
The CHAC CQD5NEZ DC isolator switch is designed for circuit isolation at up to 1500V DC. Two frame sizes cover rated currents from 80A to 630A, with front or side operation to suit the equipment layout.
Compare CQM5NEZ for the required function
Pemutus sirkuit CHAC CQM5NEZ DC tersedia dengan unit trip magnetik saja atau termal-magnetik untuk rangkaian DC 1500V. Pilih versi termal-magnetik jika memerlukan perlindungan overload maupun short-circuit. Frame 350A dan 630A mencakup arus nominal mulai dari 63A hingga 630A, dengan kapasitas pemutusan yang ditentukan oleh frame dan versi M/H.
Need Help Specifying CQW5NEDZ?
Send the circuit requirements, selected configuration, destination market and quantity for a model-specific review.
Match the frame to switching and fault-withstand duty
The three frames differ in more than current. Compare utilization category, short-time withstand duty, dimensions and connection spacing. The 100kA/1s value belongs to the 4000 frame and must not be generalized across the range.
Define the control supplies before cabinet wiring
State the voltages for the motor mechanism, closing and release functions and the required signaling. Where control voltages differ, follow the separate-supply requirements in the approved drawing. Confirm the ready-to-close and interlock logic before commissioning.

CQW5NEDZ Product FAQ
What is the difference between Icw and breaking capacity?
Icw describes short-time withstand duty for a stated duration; it does not describe automatic fault interruption. CQW5NEDZ is a DC frame isolation switch, so the fault-clearing device and coordination must be specified separately.
Does every CQW5NEDZ frame have a 100kA rating?
No. The one-second withstand values are 50kA for the 1600 frame, 85kA for the 2500 frame and 100kA for the 4000 frame. Use the exact frame and duration in the design review.
Can all operating accessories share one control supply?
Only when the selected accessory voltages and circuit design permit it. The product instructions require appropriate separate supplies if the control voltages differ. Confirm the motor, closing and release requirements against the exact wiring diagram.
Can I choose CQW5NEDZ 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 CQW5NEDZ; do not assume that every device called an isolator has the same load-break capability.
What information is needed for a CQW5NEDZ 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 CQW5NEDZ 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.
