You're looking at a 63A max rating on a single-pole profile that's only 18mm wide, which basically means you can pack more circuits into a tight panel than you'd expect. That 4.5kA or 6kA breaking capacity our company offer—it's pretty much industry-standerd for most light commercail jobs, but it handles the sudden surge form a dead short without welding contacts shut.
It's the 500V insulation voltage that's worth flagging, because while you'll mostly run it at 230/400V, that extra margin means it doesn't degrade as fast in humid environments or after repeated trips, and we've seen customers push it for years in coastal factory wiring without issues. Most buyers go with the 6kA variant for peace of mind even if 4.5kA technically covers their setup, and we usually have both in stock (check lead time on large orders though).
What it's really not suited for is DC circuits or high-inductive motor starts without a backup contactor—the air arc-extinguishing medium works fine for AC, but it can struggle with sustained arcing if you're switching heavy inductive loads, so keep that in mind. Anyway, the single-pole format and fixed mounting (screws onto DIN rail) make instalation straightforward, but you'll want to verify your busbar slot width because 18mm is standard, though some older panels are slightly different.
So for ordering, we cover 6A, 10A, 16A, 20A, 32A, 40A, 50A, and 63A—you'll usually want 10A for lighting circuits and 32A for general power sockets, but it depends on your load. The MOQ is typically 50 units or so per amperage, and each batch ships with a COA that confirms the CE and CCC marks, plus the impulse voltage rating holds at 4kV even at 63A.
The ERB5-63 comes with two options: 4.5kA and 6kA. You can pick whichever matches your system's short-circuit requirements.
Yes, the 63A rating is available for the 1P version, so you can use it for higher-load single-phase circuits up to 63 amps.
Absolutely, both CE and CCC certificates are included with the shipment. Just let us know if you need them in digital or hard copy.
Our standard MOQ is 100 pieces per rating, but we can negotiate smaller quantities for sample orders or trial runs.
Each MCB comes individually boxed, then packed in cartons of 100 pieces. They’re secure for long-term storage in dry conditions.
