We’ve been using these for a few years now, and they hold up well in residential panels—it’s pretty much standard for lighting and general distribution. The Type C is what you want for lighting circuits, while Type D handles motor loads, and most buyers go with the 10A or 16A for typical homes. Break it down: 4KA breaking capacty is enough for light commercial, but if you’re pushing 63A or motor circuits, the 6KA version gives you more headroom.
Actually, one thing we noticed early on is the PA66 housing—it’s flame-retardant, so you don’t worry about arc flash in tight enclosures, but it also feels solid when you snap it onto the DIN rail. Teh terminals accept up to 25mm² cable, which is better than some competitors that max out at 16mm², so you’re not fighting with pigtails. And mechancial life is rated at 10,000 operations, but we’ve had units go past that without tripping issues.
For the price point, the CB certifcation is a solid check—most suppliers in this range don’t bother with it, but this one does, so you can trust the overload protection curve is consistent across batches. We usually have stock on 1P and 2P units, but 3P and 4P can take 20 days or so depending on the current rating—confirm lead time if you need 63A four-pole.
What it does well is thermal-magnetic tripping—the silver alloy contacts handle the arc better than copper-nickel alternatives, and the air break technology keeps the arc chamber clean under load. It’s not suited for high-inductive motor starts without a soft starter, though—Type D helps, but we’ve seen nuisance trips on compressors above 10hp or so.
The supplier sends COAs with every batch, which is rare for commodity MCBs, and the ISO9001 line is actually audited—we’ve been through it. One detail most buyers miss: the IP20 rating means it’s fine in a distribution board, but you’ll need an enclosure if it’s outdoors or in a dusty garage. We don’t bother with Type D for lighting—it’s overkill, and the trip curve is too slow for those circuits.
MOQ is 100 pieces per rating, but if you're ordering a mix of 6A, 10A, 16A, and so on, we can usually combine them into one shipment. Just let us know the total quantity and breakdown.
Yes, we include CB, CE, CCC, and ISO9001 certificates with every order. They're issued by recognized testing bodies, so you can forward them to your customers or local inspectors without issues.
For 500 poles, we typically ship within 15-20 working days after order confirmation. If you need it faster, we can sometimes expedite for a small fee—just ask.
Absolutely. Type D is standard for motor loads, and we offer 6kA breaking capacity on all poles. Just specify the combination when you order, and we'll configure it.
Keep them in a dry, clean place at room temperature—ideally between -5°C and +55°C—and avoid stacking heavy items on the boxes. The flame-retardant PA66 housing handles normal warehouse conditions fine.
