4. 인증 준수: 북미 시장용, UL-certified models (예를 들어, 315FM) are recommended; for the European market, prioritize IEC/BS88 standards.
5. 설치 방법: Confirm the type of fuse holder (예를 들어, DIN rail-mounted, bolt-mounted) to avoid size incompatibility.
6. 기술 지원 및 문서

설치 지침:

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

– 교체 후, perform no-load and load tests to ensure good contact.

1. 메모

교체 호환성: Fuse elements from different series (예를 들어, NH, FM, PV) must not be mixed; strictly match the original model.

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

Price Fluctuations: Bulk purfor 100 units is $158.40 단위당.
