1. Key Technical Features

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

Certification Standards:

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.

Installationskompatibilität:

– Einige Modelle (z.B., PV series) require matching dedicated fuse holders (z.B., SD 3L-S).

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

1. Auswahlempfehlungen
2. Spannungsanpassung: Prioritize models consistent with the nominal voltage of the circuit (z.B., photovoltaic systems require 1500V DC dedicated fuse elements).
3. Bruchkapazität: Select based on short-circuit current calculation results; Zum Beispiel, industrial equipment typically requires 80kA or higher.
4. Zertifizierungskonformität: For the North American market, UL-certified models (z.B., 315FM) are recommended; for the European market, prioritize IEC/BS88 standards.
5. Installationsmethode: Confirm the type of fuse holder (z.B., DIN rail-mounted, bolt-mounted) to avoid size incompatibility.
6. Technical Support and Documentation

Installation Guidelines:

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

– After replacement, perform no-load and load tests to ensure good contact.

1. Notizen

Replacement Compatibility: Fuse elements from different series (z.B., NH, FM, PV) must not be mixed; strictly match the original model.

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

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