You’re dealing with downstream equipement getting fried form line surges, and standard MCBs just trip on overcurrent. 10kA breaking capacity across the 6-63A range, 1 to 4 poles. Operates at 230/400V AC, 50/60 Hz. We’ve got the overvoltage protection built in—it’s not a separate add-on module, which just cuts panel space and wiring time.
Mechanical life is 10,000 operations, and we see that hold up in commercial buildings where the breaker cycles maybe twice a week (not daily). The PA66 nylon housing is flame-retardant, good for up to 55°C ambient. Basically the arc is quenched in air, not gas—simple, reliable, no refill worries. We usually see most buyers go with the 6A or 32A options for lighting and general power circuits.
It’s compliant with IEC60898-1 and GB10963.1—we have CE, CB, CCC, and ISO9001 certs on file. Tighter tolerance on the overvoltage trip than some generics—about 275-285V instead of the usual 290V. You’ll want B curves for resistive loads or lighting, C for motors or transformers, and D for high-inrush. Here’s a thing: the 10kA rating means it actually handles a hard short without failing open—at 400V it’s no joke.
For ordering, you pick the pole count (1/2/3/4) and the trip curve (B/C/D) along with the rated current (6-63A). Custom printing on the side or a specific MOQ of 100 units or so might be needed for special lots. our company can do OEM labelling—no markups on that—but lead time swings roughly 15-20 days depending on the week.
Shiping is typically on DIN rail trays in polybags, so they won’t get banged around if it’s a standard carton. We don’t seal wire connectors here. In most cases, the housing stays rigid after 5 years in a humid panel—PA66 doesn’t wick moisture like polycarbonate. One small thing: you’ll want torque driver specs for terminals (usually 1.2-1.5 N·m is enough, any more and you strip the PA66 screw holes).
Yes, the 10KA breaking capacity applies across the entire 6-63A range, so you get consistent protection whether you're using a 6A or 63A unit.
It's certified to CE, CB, CCC, and ISO9001 standards. We can share digital copies of the certificates upon request for your audit needs.
It clips directly onto a standard 35mm DIN rail—no adapter needed. Just snap it on and you're set.
Our MOQ is typically 100 pieces per model, but it can flex a bit depending on the pole count and current rating you need. Just let us know your mix.
Yes, it's rated for up to 55°C ambient with no derating required. The flame-retardant PA66 housing keeps it stable even in warmer panels.
