1. Recomendaciones de selección
2. Coincidencia de voltaje: Prioritize models consistent with the nominal voltage of the circuit (p.ej., photovoltaic systems require 1500V DC dedicated fuse elements).
3. Capacidad de ruptura: Select based on short-circuit current calculation results; Por ejemplo, industrial equipment typically requires 80kA or higher.
4. Certification Compliance: For the North American market, UL-certified models (p.ej., 315FM) are recommended; for the European market, prioritize IEC/BS88 standards.
5. Método de instalación: Confirm the type of fuse holder (p.ej., 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 (p.ej., the arrow on PV series should align with the current flow).

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

1. Notas

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

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