We usually keep the common configurations like 1P and 2P in 16A and 32A in stock, so lead time is about 5-7 working days for those, but if you need 4P in 63A with D-curve, that's typically a 20-day or so production run—check lead time before ordering. The DIN rail mounting is pretty straightforward, just snaps right on, and the 17.5mm width per pole means a 4P unit takes up 70mm on the rail, which some buyers don't realize until they're laying out the panel.
What it does is handle overload and short-circuit protection up to 6kA breaking capacity, and you've got the choice between B, C, or D tripping curves depending on your load—most buyers go with the C-curve for general distribution since it handles inrush better. The terminal clamps accept wire from 1 to 35mm², which is fine for most residential or light commerical runs, but it's not suited for heavy industiral feeders where you'd need a higher kAIC rating—just something to keep in mind if you're looking at transformer secondaries.
8,000 electrical operations is the rated life, and while that sounds low, it basically matches what we see in field use over 10-15 years in a typical panelboard—nobody's cycling these daily. operating temperature range from -40°C to +50°C covers most environments, but if you're mounting it outdoors in direct sun, the IP20 rating means it's not sealed against moisture, so you'll want an enclosure.
Anyway, the certifications include CE, CB, CCC, and RoHS, so you're covered for most export markets, and we provide COAs with each batch—just specify if you need the HPLC data or just the standdard pass/fail. We've been shiping these for years, and one thing a few buyers miss is that the 1P and 2P units have a slightly different terminal torque spec—5.0 Nm versus 4.5 Nm for the 3P and 4P—so double-check your installation instructions if you're mixing poles.
For pricing, the MOQ on the 4P units is 50 pieces, but on the 1P and 2P our company can do smaller lots—say 20 or so—though the per-unit cost jumps a bit. We usually ship via sea freight for bulk orders, roughly 30-45 days, or air if you're in a hurry, but that adds about 15% to the total. Just send over your exact pole count and amperage mix, and we'll quote you with the 6kA option unless you specify the 4.5kA for lighter duty.
Lead times for mixed pole orders usually run 15-20 working days after order confirmation, depending on stock levels. We keep 1P and 2P models in higher stock, so those ship faster. For larger 4P quantities, we may need a production slot.
Our MOQ is 50 units for standard 1P and 2P models, and 20 units for 3P and 4P. Custom current ratings like 6A or 63A don't change the MOQ, but we do ask for a bit more lead time on less common ratings.
Yes, we include CE, CB, CCC, and RoHS certificates in the packing list, and we can email you scanned copies before shipping. If you need original hard copies, just let us know in the order notes.
It's rated for -40°C to +50°C, so 45°C is fine — no derating needed at that temp. Just make sure the DIN rail is in a ventilated panel to keep heat from building up around the terminals.
Terminals accept 1 to 35 mm² wire, and they work with both solid and stranded copper. We recommend using a ferrule for stranded wire under 6 mm² to get a clean, tight connection.
