How to Select a 400A DC MCCB for a 2 Pole Circuit
Specify the DC operating voltage, required current, 2P order code, fault level and connection arrangement when requesting a WLM7DC-400 quotation from W9 Group.
Specify DC circuit conditions
State maximum system voltage, fault current and source arrangement. Request DC ratings for the exact pole connection.
選択した電流を指定してください
The 400 frame schedule lists 250, 280, 315, 320, 350, 400 A. Confirm the required current and trip-unit version.
Coordinate fault interruption
Confirm Icu and Ics at the intended DC operating voltage rather than using the insulation voltage as the operating rating.
パネルの統合を確認する
Request dimensions, terminals and the installation drawing for the quoted 2P version. Confirm accessories separately.

購入者のよくある質問
WLM7DC-400 DC MCCB FAQs: Current, Voltage and Fault Rating
Find answers about WLM7DC-400 selection, configuration and ordering.
Which configuration does this WLM7DC-400 page cover?
The product summary identifies 400 A and 2P. The frame schedule contains several current choices, so confirm the full order code and selected current.
What current options are listed for WLM7DC-400?
The target-page frame schedule lists 250, 280, 315, 320, 350, 400 A. These are catalog choices rather than one adjustable range guaranteed for every trip unit.
Can the insulation voltage be used as the DC operating voltage?
No. The listed insulation voltage describes insulation performance. Confirm the separate DC operating voltage, pole arrangement and breaking capacity from the matching datasheet.
How should I choose DC breaking capacity?
Provide the system voltage and prospective fault current. Ask W9 Group for Icu and Ics at that voltage and for the required connection arrangement.
Is the AC voltage table sufficient for DC selection?
No. Some target-page table headings are inconsistent. Confirm the dedicated DC rating schedule and wiring diagram for the offered breaker.
Does this breaker include remote monitoring?
A supported interface is not established for this exact configuration. Confirm any communication accessory, auxiliary supply and interface documentation before including remote monitoring in the specification.
What is needed for a WLM7DC-400 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。.
