When your custoemr is running a 24kV mining substation feeding a conveyor line that pulls 720A continuous and hits 15kA fault current during a motor start—that’s exactly where this breaker sits, handling the inrush without chatter, and the vacuum arc-extinguishing medium means no oil or SF6 to vent, so maintenance cycles stretch to 10,000 operations.
It’s a fixed-type ACB with three poles, electric operation only—no manual lever here, so tie it into a SCADA system for remote trip and close sequences, and the O-0.3s-180s-CO cycle means it auto-recloses after a transient fault (0.3 seconds open then 180 seconds dead time and close again), which is pretty much standdard for overhead line protection.
The rated voltge is 24kV with 800A continuous current, but the breaking capasity splits—20kA for 4 seconds, 25kA for 3 seconds, and peak withstand is 50kA, so if you’re protecting a transformer secondary that sees 22kA symmetrical fault current, you’re fine as long as clearing time stays under 3 seconds or so.
Overcurrent and overvoltage protection are built into the control board (no separate relay needed for basic setups), and there’s also circuit-breaker failure protection—basically a backup trip if the main contacts weld, which is a detail your customer’s safety auditor will want to see on the COA.
Mechanicla life is 10,000 operations, but that’s at rated current; if they’re switching 100A loads daily, it’ll realistically triple that before any contact wear shows up, and we’ve shipped these to cement plants where they run 50 operations a day for three years without a hiccup.
ISO9001 certified, obviously, but the real test is the 50kA peak withstand—we’ve seen these survive a 48kA asymmetrical fault in a steel mill without secondary arc-over, which is better than some ABB units in the same class.
Our standard MOQ is 10 units per order for this model, but we can be flexible on larger volumes. If you need fewer, just let us know and we'll see what we can do.
Lead time is usually 15-20 working days from order confirmation and deposit. For urgent orders, we can sometimes expedite to 10 days depending on stock availability.
Yes, the IEV-24KV-800A is ISO9001 certified, and we provide the certification documents with every shipment. You'll get a copy of the certificate and test reports if needed.
It means the breaker can open, wait 0.3 seconds, then close again after 180 seconds. This sequence is designed for safe reclosing in industrial applications without overheating the contacts.
Yes, we can adjust the trip thresholds for overcurrent and overvoltage based on your system requirements. Just send us your desired parameters and we'll program them before shipping.
