1. 選択の推奨事項
2. 電圧マッチング: Prioritize models consistent with the nominal voltage of the circuit (例えば, photovoltaic systems require 1500V DC dedicated fuse elements).
3. 遮断容量: Select based on short-circuit current calculation results; 例えば, industrial equipment typically requires 80kA or higher.
4. 認証への準拠: 北米市場向け, UL-certified models (例えば, 315FM) 推奨されています; for the European market, prioritize IEC/BS88 standards.
5. 設置方法: Confirm the type of fuse holder (例えば, DIN rail-mounted, bolt-mounted) to avoid size incompatibility.
6. Technical Support and Documentation

設置ガイドライン:

– Ensure power is disconnected and verify with a voltage tester before operation. Pay attention to the direction of the fuse element during installation (例えば, the arrow on PV series should align with the current flow).

– 交換後, perform no-load and load tests to ensure good contact.

1. 注意事項

交換互換性: Fuse elements from different series (例えば, NH, FM, PV) must not be mixed; strictly match the original model.

Inventory Inquiry: For urgent needs, it is recommended to contact distributors directly (例えば, via WhatsApp: 0086-13811255435) to confirm spot availability in Los Angeles warehouses.

Price Fluctuations: Bulk purfor 100 units is $158.40 ユニットあたり.
