1. Caratteristiche tecniche principali

Capacità di interruzione: Ranging from 80kA (tipo base) to 200kA (high-spec models), selection should be based on the short-circuit current of the circuit.

Standard di certificazione:

Certificazione UL: 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.

Compatibilità di installazione:

– Alcuni modelli (per esempio., PV series) require matching dedicated fuse holders (per esempio., SD 3L-S).

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

1. Raccomandazioni per la selezione
2. Corrispondenza della tensione: Prioritize models consistent with the nominal voltage of the circuit (per esempio., photovoltaic systems require 1500V DC dedicated fuse elements).
3. Capacità di interruzione: Select based on short-circuit current calculation results; Per esempio, industrial equipment typically requires 80kA or higher.
4. Conformità alla certificazione: Per il mercato nordamericano, UL-certified models (per esempio., 315FM) sono raccomandati; for the European market, prioritize IEC/BS88 standards.
5. Metodo di installazione: Confirm the type of fuse holder (per esempio., DIN rail-mounted, bolt-mounted) to avoid size incompatibility.
6. Technical Support and Documentation

Linee guida per l'installazione:

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

– Dopo la sostituzione, perform no-load and load tests to ensure good contact.

1. Note

Compatibilità di sostituzione: Fuse elements from different series (per esempio., NH, FM, PV) must not be mixed; strictly match the original model.

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

Price Fluctuations: Bulk purfor 100 units is $158.40 per unità.
