How to Select a JCB3-63DC DC MCB by Pole Voltage 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.

購入者のよくある質問
JCB3-63DC DC MCB FAQs: Pole Wiring, DC Voltage and Breaking Capacity
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?
必要な構成、数量、配送先市場、および書類の要件を送信してください。W9 Groupに、選択した構成の価格、最小注文数量、サンプル、納期を確認していただくよう依頼してください。.
