Gabay sa Pagpili at Aplikasyon
When selecting a panel fuse holder, first confirm the fuse size, system rated voltage, operating current and required installation method. This dual-design model supports both panel and board mounting, which can effectively reduce procurement types for projects with mixed assembly requirements. Choose a 5x20mm fuse with appropriate current rating based on actual load, and reserve a 1.25–1.5 times safety margin to prevent overheating during continuous operation. For front-panel fuse replacement scenarios, use the panel mount method; for high-integration circuit board designs, use the PCB board mount method. For flame retardant and insulation-sensitive scenarios, prioritize products with UL94 V0 grade housing and high insulation resistance to ensure operational safety.

Mga Tagubilin sa Pag-install at Pagpapanatili
1. Pumili ng 5x20mm na cartridge fuse na may tamang current at voltage rating ayon sa mga kinakailangan sa proteksyon ng circuit.
2. For panel mount: Drill a standard mounting hole on the equipment panel, insert the fuse holder from the front side, and tighten the fixing nut from the back to ensure firm installation.
3. For board mount: Insert the terminal pins into the corresponding PCB holes, and ensure proper soldering quality to avoid cold solder joints that cause increased contact resistance.
4. Ipasok nang buo ang piyus sa lalagyan at higpitan ang takip sa dulo upang matiyak ang maaasahang pagganap ng contact at insulation.
5. Huwag gumamit ng higit sa itinakdang boltahe at kasalukuyang saklaw upang maiwasan ang pagkasira ng insulasyon at mga panganib sa kaligtasan.
6. Tanggalin nang tuluyan ang suplay ng kuryente bago palitan ang fuse upang maiwasan ang electric shock at short circuit damage.
7. Pana-panahong siyasatin ang mga terminal at piyus para sa mga senyales ng pagkaluwag, oksihenasyon, o sobrang pag-init, at palitan agad ang mga bahagi kung may matagpuang abnormalidad.
