1. Caracteristici tehnice cheie

Capacitate de rupere: Ranging from 80kA (basic type) to 200kA (high-spec models), selection should be based on the short-circuit current of the circuit.

Standarde de certificare:

UL Certification: Models such as 315FM and PV-315A-3L-15 are suitable for the North American market.

IEC/BS88: European and internationally recognized standards, applicable to models like 170M3067 and 315BMT.

Compatibilitate cu instalare:

– Unele modele (de ex., Seria PV) require matching dedicated fuse holders (de ex., SD 3L-S).

– Dimensions comply with DIN 43620 (seria NH) or BS88 (FM series) standardele.

III. Canale de achiziție și referință de preț

1. Recomandări de selecție
2. Potrivirea tensiunii: Prioritize models consistent with the nominal voltage of the circuit (de ex., photovoltaic systems require 1500V DC dedicated fuse elements).
3. Capacitate de rupere: Select based on short-circuit current calculation results; de exemplu, industrial equipment typically requires 80kA or higher.
4. Conformitatea cu certificarea: Pentru piața nord-americană, UL-certified models (de ex., 315FM) sunt recomandate; for the European market, prioritize IEC/BS88 standards.
5. Metoda de instalare: Confirm the type of fuse holder (de ex., DIN rail-mounted, bolt-mounted) to avoid size incompatibility.
6. Suport tehnic și documentație

Ghid de instalare:

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

– După înlocuire, perform no-load and load tests to ensure good contact.

1. Note

Compatibilitate de înlocuire: Fuse elements from different series (de ex., NH, FM, PV) must not be mixed; strictly match the original model.

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

Price Fluctuations: Bulk purfor 100 units is $158.40 pe unitate.
