Low Voltage High Capacity Air Circuit Breaker 400V/690V for Commercial Electrical Applications

We typically see cycle times around 20 days or so for the fixed frame versions, though drawer types might push it to 30, and our company can talk about that depending on your batch size and whether you need 3P or 4P.

Every unit gets an HPLC-certified COA pulled from the batch before it ships — we don’t cut corners on that, and you’ll get the full test report with each order, but what it does is let you verify the injection profile against your own reference if you need to.

The 400V rating usually covers most commercial setups, and the breaking capacity runs form 50 up to 100kA depending on the model, so it’s actually better than a lot of the older gear for arc flash margin, but don’t use it in a DC enviornment because the contacts aren’t designed for that.

One thing we’ve found is that the mechanicla life at 30,000 operations ends up being the limiting factor before the electrcial life at 6,500 cycles — most buyers go with the 1000A frame for the shorter contact wear, anyway — but our company offer a one-time retest policy if you see drift in the first three months.

Communication is handled via Modbus, Profibus-DP, or Device Net straight out of the box, so you’ll want to specify the protocol when you place the PO since swapping the controller module after fact adds about a week to lead time and costs extra for the adapter harness.

We ship with the standdard IEC60947-2 and GB/T14048.2 marks on the nameplate, factory-sealed in a plywood crate with the drawer unit separate (if you order that option), so just confirm your connection direction and whether you need the horizontal or vertical bus bar kit.
