VGC series Fuses
The VGC series are compact high-voltage fuses supporting up to AC1000V/DC800V, providing safe, efficient, and flexible circuit protection.
Fuses
VOZWEI manufactures industrial fuses for solar PV, wind power, energy storage and low-voltage distribution. Compact VGC fuses cover 2–125 A, up to 1000 V AC / 800 V DC; NT fuses cover 2–1600 A at 800 V AC, with breaking capacity up to 120 kA. Both ranges offer gG/gL (full-range), aM (motor circuits) and aR (semiconductor protection) fuse classes.
FAQs
Q: Which VOZWEI VGC and NT fuse series are available?
A: VOZWEI offers two fuse series: the VGC compact fuse spans In 2A–125A in 14x51mm and 22x58mm sizes with AC400/500/690/1000V and DC440/800V ratings; the NT industrial fuse spans In 2A–1600A at AC800V. Both comply with IEC 60269.
Q: What are the main differences between VOZWEI VGC and NT fuses?
A: The VOZWEI VGC is a compact fuse for equipment and loop protection, 2A–125A in 14x51mm and 22x58mm sizes, with classes gG/gL, aM and aR. The VOZWEI NT is a wide-range industrial fuse, 2A–1600A at AC800V, with classes gG/gL, aM and aR.
Q: How do VOZWEI VGC and NT fuses differ on DC rating?
A: VOZWEI VGC fuses carry both AC and DC ratings (AC400/500/690/1000V, DC440/800V) with DC breaking capacity up to 50kA, suitable for solar DC circuits. The VOZWEI NT series is AC800V only with no DC rating and targets AC heavy-duty industrial circuits.
Q: How do I choose VOZWEI VGC or NT fuse rating?
A: For VOZWEI VGC or NT fuses, size In to the continuous load current, conductor ampacity and fuse characteristics, accounting for inrush. Pick a voltage that covers the system (VGC: AC400/500/690/1000V and DC440/800V; NT: AC800V), confirm breaking capacity exceeds the prospective fault current, and choose class by load type.
Q: Should I use VOZWEI VGC or NT for DC440/800V solar?
A: Use a VOZWEI VGC fuse for DC440V or DC800V solar circuits, since VGC carries DC440/800V ratings with DC breaking capacity up to 50kA. The VOZWEI NT series is AC800V only and not for DC; pair VGC with the VRB14 or VRB22 holder (AC1000V).
Q: What do gG/gL, aM and aR mean on VOZWEI fuses?
A: Fuse classes define protection targets. The gG/gL class covers general line protection, aM covers motor circuits and aR covers semiconductor circuits. Both VOZWEI VGC (2A–125A) and NT (2A–1600A) use these three classes.
Q: Which applications suit VOZWEI VGC and NT fuses?
A: The VOZWEI VGC compact fuse suits equipment and loop protection in solar and modern energy systems at 2A–125A with AC400/500/690/1000V and DC440/800V options. The VOZWEI NT industrial fuse targets heavy-duty circuits at 2A–1600A and AC800V. Both comply with IEC 60269.
Q: When should I use VOZWEI NT fuse over VOZWEI MCCB?
A: Use a VOZWEI VGC or NT fuse where very high breaking capacity is needed in a compact body and one-time protection is acceptable; use a VOZWEI MCB or MCCB where the circuit must be reset and reused. VOZWEI fuses reach up to 120kA breaking capacity.
