You're looking at something that basically sits a large power distribution setup, handling everything from 400A up to 4000A depending on which model you pick. It's an air-based circuit breaker, electric operation, built for AC systems running 50Hz.
What it does is protect against the big failures—overload, short circuit, undervoltage, and even single-phase grounding—while also acting as a physical isolation switch. Most buyers in industrial plants or data centers go with the 3P or 4P configuration, and the full breaking time is 12-35ms, which is pretty quick for this class.
Rated working voltge runs from AC400V all the way to AC1500V, with insulation voltage at 1250V or 1500V. The impulse withstand is 12kV or 14kV, and it passes a 3500V, 50Hz, 1-minute industiral frequency test. Mechanicla life is typically 10,000 to 20,000 operations, though electrical life drops to 500-2000 depending on the current you're switching.
It's not the best choice for small residential panels—these are big, modular units meant for substations or main distribution boards. The wide pole spacing and zero flying arc distance are details you'll appreciate during installation, especially when you're working with horizontal or vertical wiring setups.
We've got CQC certification and compliance with GB/T14048.1 and GB/T14048.2, so you're covered on standard side. Lead time is usually 20 days or so for standard models, but confirm if you need a custom wiring configuration or a specific communication protocol integrated.
Closing time stays under 60ms, and the arc-extinguishing medium is air, so no special gas handling required. One thing buyers don't always ask about is the single-phase grounding protection—it's built in, not an add-on, which saves you a separate module.
We can do a small MOQ of 10 units for initial orders on the ARW3-1600, but for the ARW3-2500 and ARW3-4000 it's typically 5 units due to higher demand. We're flexible if you're testing the market.
For a mixed order under 50 units, lead time is around 15-20 working days after deposit. Custom voltage or pole configurations might add 5-7 days.
Yes, we include CQC certification and full GB/T14048.1-14048.2 test reports with every shipment. We'll email them ahead of delivery so your team can verify.
At AC1000V and full rated current, the ARW3-2500 breaks in 20-35ms. The 12ms minimum applies to lower currents around 400A. We can provide a time-current curve chart for your specific voltage.
Each breaker ships in an individual cardboard box with foam inserts. Store them in a dry, ventilated area at -25°C to 55°C. Avoid stacking more than 4 boxes high to prevent damage to the terminals.
