راهنمای انتخاب
Selecting a JCB3-63DC DC MCB by Current, Poles and Polarity
Specify the current, trip curve, DC voltage, pole wiring, polarity, fault level and accessory requirements when requesting a JCB3-63DC quotation from W9 Group.
Select the DC current and curve
Use the table current choices and confirm the selected B or C curve against load startup and protection coordination.
Match voltage and pole wiring
Select the pole arrangement for the system voltage and obtain the required series connection and earthing diagram.
Confirm polarity and reverse current
The title and body give inconsistent polarity descriptions. Request the exact terminal marking and allowed current direction for the supplied version.
Check fault duty and accessories
Confirm DC fault capacity, circuit time constant where applicable, installation conditions and each ordered accessory code.

سوالات متداول خریداران
JCB3-63DC DC Miniature Circuit Breaker FAQs: Voltage and Polarity
Find answers about JCB3-63DC selection, configuration and ordering.
Which currents are listed for JCB3-63DC?
The electrical table lists 6, 10, 16, 20, 25, 32, 40, 50 and 63 A. The prose mentions a broader lower-end range; use a confirmed order schedule for any additional current.
Does every pole version have the highest DC voltage rating?
No. The table assigns different DC voltages to different pole arrangements. Confirm the required pole connection and operating voltage for the selected version.
Is JCB3-63DC polarity sensitive?
The native title calls it polarity DC while body prose says it is not polarity sensitive. Confirm the actual terminal markings, wiring diagram and permitted current direction before installation.
What does the listed breaking capacity establish?
The table lists 6 kA. Confirm the applicable DC voltage, pole arrangement, test conditions and project fault duty for the ordered breaker.
Does the DC breaker replace residual-current or insulation monitoring?
Do not infer those functions from overload and short-circuit protection. Confirm any additional monitoring or protection required by the system design.
Which standard and accessories should be specified?
The summary and body use different standard references. Request the exact-model test documents and confirm each auxiliary contact, alarm or release by its matching accessory code.
What is needed for a JCB3-63DC quotation?
اطلاعات مورد نیاز را، تعداد، بازار مقصد و الزامات اسناد را ارسال کنید. از W9 Group درخواست کنید تا قیمت، حداقل مقدار سفارش، نمونه‌ها و زمان تحویل برای پیکربندی انتخاب شده را تأیید کند.
