What really stands out here is the 7500A operating short-circuit current rating — that's not something you see every day on a manual breaker in this class.
It's a 4-pole fixed unit 400V operating and 800V insulating voltage, with a 10000A ultimate breaking capacity. The rated current range runs form 1A to 63A, so you've got flexibility depending on your load. And the arc-extinguishing medium is air, which keeps things simple and reliable for industrial environments.
Basically, this thing is built for heavy industrial protection where you need high-speed manual interruption. Most buyers go with the 4-pole version for three-phase plus neutral setups. It's not really suited for residential panels or anything below 400V systems give or take.
You'll get it in a standard carton, usually with the breaker and basic mounting hardware. We typically have stock on the common ratings — 16A, 32A, 63A — but confirm lead time for odd sizes like 1A or 6A (usually 2-4 weeks). Cerification covers ISO9001, CE, CB, and CCC, so compliance isn't an issue for most markets.
One thing a buyer might not think to ask: teh manual operation handle has a positive feel — you can hear it click into position. It's a small detail but matters when you're doing fault isolation in a panel.
Anyway, if you're speccing a 7500A operating short-circuit capability, this delivers that without needing a larger frame. The 63A max is limit though — don't push it past that for continuous duty.
We typically start bulk orders at 100 units, but if you need less, let us know — we might be able to work something out depending on stock.
Yes, we carry ISO9001-2000, CE, CB, and CCC certifications. We can share copies of the certificates with your order.
For orders under 500 units, lead time is around 15-20 working days. Larger quantities may take 25-30 days, but we'll confirm once we know your volume.
Sure, we can do custom carton packaging with your logo or branding for bulk orders. Just send us the design, and we'll handle the rest.
The rated short-circuit current is the maximum fault current the breaker can safely interrupt once. The operating short-circuit current (7500A) is the level it can handle repeatedly without damage — so that's your go-to for regular use.
