選定ガイド
Selecting a 275V AC SPD with 20kA In and 40kA Imax
Specify the supply voltage, earthing system, pole arrangement, SPD classification and backup protection when you request a JCSD-40 quotation from W9 Group.
Match the supply network
For JCSD-40, specify single-phase or three-phase supply and the earthing arrangement so the connection scheme can be confirmed.
Check surge ratings
Compare Uc, Up and discharge-current ratings in the matching datasheet; confirm classification and any impulse-current rating required by the project.
Check protective coordination
Ask for the required backup protection, conductor sizing and installation connection drawing for the selected SPD.
Plan inspection and replacement
Request status-indicator instructions, replacement-module compatibility and any remote indication option for the offered version.

Where is JCSD-40 intended to be used?
The supplier table identifies AC supply circuits. Confirm the supply voltage, earthing arrangement and connection layout for the selected device.
What do In and Imax mean on this page?
They are the nominal and maximum discharge-current labels in the supplier table. Use the associated test data when comparing SPDs; confirm the required project classification separately.
How should I specify the version?
State JCSD-40, supply voltage, earthing arrangement, pole count and required SPD classification; request the corresponding datasheet.
What is needed for a JCSD-40 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。.
What is JCSD-40 used for?
The supplier tables identify this model family for AC supply circuits. Confirm the supply voltage, earthing arrangement and connection layout for the selected device; the page does not certify a universal installation.
How should I compare In and Imax when selecting an AC SPD?
Use the supplier table’s nominal and maximum discharge-current labels together with the project classification and test data. Confirm the required SPD class and wiring before ordering.
