Why this FAQ?
Engineers asked for a concise, spec-true reference to select and install a 1500 Vdc, 3L PV fuse. This summarizes ratings, approvals, fitment, and buying info without fluff.
[faq question=”What is the Eaton Bussmann PV-315A-3L-15 and typical applications?”]A gPV high-speed fuse-link for photovoltaic DC protection, rated 315 A at up to 1500 Vdc in the 3L form factor. It protects PV strings, combiners, DC disconnects, and inverter DC inputs from overloads and short-circuit faults. Use in 1500 Vdc PV arrays; not intended for AC circuits.[/faq]
[faq question=”What are the key electrical ratings and performance?”]Rated current 315 A; voltage 1500 Vdc; interrupting rating 100 kA (verify test conditions in datasheet). Fuse class gPV (full-range PV protection) with high-speed characteristics. Typical power loss 52 W (at rated current). For time-current and I²t data, refer datasheet / contact Shansen.[/faq]
[faq question=”Which standards and certifications does it meet?”]Compliances include IEC 60269 (gPV), UL Listed, CSA Certified, CE Marked, and RoHS compliant. Use these approvals for project documentation and AHJ submissions. If a specific clause/part is required, refer datasheet / contact Shansen for confirmation.[/faq]
[faq question=”What are the physical details and connections?”]3L blade-type fuse-link with ceramic body, white color, with indicator window. Weight approx. 2035 g. Dimensions are listed as 75×91×205 mm and also (L×W×H) 217×94×82 mm—refer datasheet for exact outline per variant. Blade connections mate with 3L fuse bases.[/faq]
[faq question=”Which fuse holder/base is compatible?”]Use with SD3L-S-PV XL 3L fuse base (or equivalent 3L, 1500 Vdc-rated holder). Ensure the base’s voltage, creepage/clearance, and terminal ratings meet 1500 Vdc/315 A and local standards. Check terminal hardware/torque in the base datasheet.[/faq]
[faq question=”What does the built-in indicator do?”]The visual indicator shows fuse-open status to aid maintenance. For remote signaling, check if the chosen 3L base supports microswitch accessories. Confirm indicator visibility/orientation in the panel layout.[/faq]
[faq question=”How should I size and coordinate this fuse in a PV system?”]Select ampere rating based on array Isc and expected operating/current-imbalance per IEC gPV guidance; verify time-current curves for clearing times. Check I²t let-through for coordination with DC contactors, busbars, and semiconductor devices. Apply ambient/temperature and enclosure derating from the manufacturer curves.[/faq]
[faq question=”Any installation and safety notes?”]De-energize and LOTO the DC circuit before replacement; use DC-rated PPE and arc-flash precautions. Mount in a 1500 Vdc-rated 3L base; tighten to specified torque; ensure ventilation and spacing. Observe polarity/clearances and re-verify insulation resistance after installation.[/faq]
[faq question=”How do I order and verify the correct part in India?”]Order by catalog number PV-315A-3L-15 (EAN 5996516001165, UPC 051712372169). Shansen Enterprises (authorized channel partner) serves Tamil Nadu with pan-India delivery and quick WhatsApp quotes. For stock, lead time, and any spec confirmation, contact Shansen.[/faq]
