응용 시나리오
GFPVT1500‑74ES series square‑body photovoltaic pv fuse 1500VDC 100‑800A gPV is designed for utility‑scale & commercial 1500VDC solar‑power systems: large‑capacity PV combiner boxes, central solar inverter DC input side, solar farm DC collection circuits and energy‑storage DC systems. It provides gPV‑grade full‑range over‑current & short‑circuit protection for solar arrays and heavy‑duty DC wiring.
Installation & Operating Notes
- Two terminal styles: bolted‑type(‑B‑74ES) for bolt fastening; din fork‑type(‑U‑74ES) for din‑mount fuse base installation.
- Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating factor when ambient temperature exceeds 40℃.
- Need current‑rating correction for high‑altitude installation above 2000 m; derate for closed‑box poor‑heat‑dissipation environments.
- Select matched copper conductor cross‑section according to rated‑current to avoid over‑heating connection terminals.
- Do NOT replace fuse under loaded DC circuit unless special load‑break switchgear is equipped.
- Replace fuse immediately if mechanical damage or housing crack is observed.
- For high‑vibration outdoor solar‑farm installations, perform extra reliability validation tests as required.
Packing & Supply
Standard bulk package. Sample testing support, OEM customization, stable mass‑volume supply for utility‑scale solar‑energy equipment manufacturers. REACH declaration available upon customer request.
