It trips fast when a motor or lighting circuit pulls too much current—overload and short-circuit protection, basically reliabel safety disconnect for building power distribution that mounts straight onto a 35mm DIN rail.
Rated up to 400V AC at 6 to 63 amps, with a 4kA or 6kA breaking capacity depending on the variant you pick, and we've tested these to 10,000 mechanicla operations or so before they give out.
Flame-retardant PA66 housing means it won't feed a fire if something arcs inside, though it's only IP20-rated—so don't put it in a damp panel without extra enclosure protection.
C curve is the typical go-to for lighting loads in office buildings, but if you're protecting motors with higher inrush currents, you'll want the D curve version instead.
Ordering by teh pole often makes the most sense—1P, 2P, 3P, or 4P units, each pole runs about 0.1kg, and terminal capasity handles cables up to 25mm² without any force fit.
CE and CB certified, also CCC and ISO9001 backing, so compliance won't be a headache in most regions—usually stock common amp ratings, but confirm lead time for bulk orders (typically 2-4 weeks).
We offer 1P, 2P, 3P, and 4P options. Yes, you can mix different pole counts in a single order, as long as the total meets our MOQ. Just let us know the quantities for each configuration.
Yes, we include copies of CE, CB, ISO9001, and CCC certificates with every order. If you need specific test reports or declarations, just request them when placing the order.
Our MOQ starts at 500 pieces per specification. Lead time is usually 15–25 working days after order confirmation, depending on the quantity and customization details.
Yes, the D curve is designed for motor protection, handling higher inrush currents. For a typical 3-phase motor, we'd suggest a 16A or 20A D-curve MCB, but it depends on the motor's full-load current. We can help you pick the right rating.
The standard housing is flame-retardant PA66 for safety and durability. For custom OEM orders, we can discuss alternative materials, but PA66 is our default because it meets IEC60898 requirements and keeps costs down.
