Q: Which VOZWEI VW3 ACB series are available?
A: VOZWEI offers four VW3 ACB series: the VW3-20 covers 200A–2000A up to AC690V, the VW3-25 covers 630A–2500A, the VW3-40 covers 1000A–4000A and the VW3-63 covers 4000A–6300A. Depending on the specific model and configuration, the latter three support AC1500V systems and break 75kA, 80kA and 85kA at AC800V.
Q: What current range does the VOZWEI VW3 ACB family cover?
A: The VOZWEI VW3 ACB family spans 200A to 6300A: VW3-20/25/40/63 cover 200A–2000A / 630A–2500A / 1000A–4000A / 4000A–6300A. VW3-20 breaks 50kA at AC690V; the VW3-25/40/63 break 75kA, 80kA and 85kA at AC800V.
Q: What is the difference between fixed and drawout VOZWEI VW3 ACB?
A: On VOZWEI VW3 ACBs, fixed type mounts the breaker directly in the switchgear; drawout type sits on a withdrawable carriage and moves between connected, isolated and withdrawn positions for maintenance. Both 3P and 4P are available across VW3-20, VW3-25, VW3-40 and VW3-63.
Q: How do I select between VOZWEI VW3 ACB frames?
A: Match the VOZWEI VW3 ACB frame to main bus current: VW3-20 for 200A–2000A up to AC690V; VW3-25/40/63 cover 630A–6300A supporting AC1500V depending on model and configuration. Only the VW3-40 also covers AC1250V; confirm breaking capacity exceeds the busbar fault level.
Q: Which VOZWEI VW3 ACB suits AC1140V or AC1500V?
A: Choose the VOZWEI VW3-25, VW3-40 or VW3-63 ACB for AC1140V or AC1500V systems; the VW3-20 stops at AC660/690V. The VW3-25 covers 630A–2500A, the VW3-40 covers 1000A–4000A and the VW3-63 covers 4000A–6300A, all built for PV, wind and energy storage AC collection.
Q: What do S, H, HU and HV mean on VOZWEI VW3 ACB?
A: On VOZWEI VW3 ACBs, S, H, HU and HV mark breaking-capacity grades within each frame. The VW3-20 offers S and H; the VW3-25, VW3-40 and VW3-63 offer H, HU and HV, with HU and HV available in 3P only.
Q: Which applications suit VOZWEI VW3-25, VW3-40 and VW3-63?
A: The VOZWEI VW3-25, VW3-40 and VW3-63 ACBs are tailored for photovoltaic, wind power and energy storage systems, supporting AC1500V depending on the specific model and configuration, with breaking capacity 75kA to 85kA at AC800V. They are rated IP40 and operate from -40°C to +70°C.
Q: When should I upgrade from VOZWEI MCCB to VW3 ACB?
A: Upgrade from a VOZWEI MCCB to a VW3 ACB when the system needs main-incomer functionality: rated current above 630A, AC1140V or AC1500V, higher breaking capacity than the MCCB can provide, or integrated protection functions. VOZWEI VW3 ACBs span 200A–6300A with breaking capacity up to 85kA at AC800V and add fixed or drawout mounting.
Q: Do VOZWEI VW3 ACBs support remote control?
A: Yes. VOZWEI VW3 ACBs integrate a communication network and support remote control for supervisory systems. Combined with overload, short-circuit (short-delay and instantaneous), ground-fault and neutral protection, they suit remote PV, wind and energy storage substations.
