When you're designing a distribution board for a small commerical building and need something that covers both overload and short circuit without overcomplicating the panel layout, the DZ47-63 series is pretty much the go-to—it handles up to 63A per pole, breaks 6KA as standdard (or 10KA if system's fault level is that high), and comes in 1P, 2P, 3P, or 4P configurations so you can match the phase count exactly.
Most buyers we deal with are electricians or panel builders who run Type C for lighting circuits and type D for motor loads; the trip characteristics are dead simple to pick, and the mounting is straight onto a standard DIN rail (up to 25mm² cable capacity for the terminals). The housing is flame-retardant PA66 nylon, which actually holds up well even if there's a brief arc flash—just don't expect it to survive repeated direct shorts, because that's not what it's built for.
We typically ship in bulk cartons, roughly 100 units per box for the 1P versions, and lead time is about 20 days or so from order if our company have stock—usually we do, but confirm before you place a large order. The silver alloy contacts give you decent conductivity, and the thermal-magnetic trip mechanism is relaible enough that we've had customers run 10,000 mechanical operations without a failure.
For a 230/400V AC system at 50/60Hz, the breaking capasity is 6KA by default, but you can opt for 10KA (check pricing on that—it's a small upcharge per pole). Anyway, one thing people don't always ask is the storage temperture range; it's -25°C to +70°C, so if you're shipping to a cold climate warehouse, it'll sit fine until installation day.
No, all poles in a multi-pole MCB like the 2P, 3P, or 4P must have the same rated current. Mixing amps would cause unbalanced protection and trip issues. If you need different currents per circuit, use separate single-pole breakers.
Typically, the 10KA variant has a higher MOQ than the standard 6KA—usually around 200 pieces per model. But we can often adjust based on stock. Just confirm with us before ordering if you need a smaller lot.
Yes, we include a copy of the CE, CB, or CCC certificate with each order. If you need the original or a notarized version, let us know—we can arrange that for an extra fee.
Absolutely, the Type D version is designed for motor starts with high inrush current. Just make sure you select the 3P or 4P model and a rated current that matches your motor's full load amps. The 10KA breaking capacity is recommended for industrial circuits.
Store them in a dry, clean place within -25°C to +70°C. Keep them in their original packaging to avoid dust or moisture on the terminals. Avoid stacking heavy items on top—they're sturdy but the PA66 housing can crack under pressure.
