For sample quantities we're looking at about $1,200 per unit, mid-volume orders of 50 pieces or so drop to roughly $850, and bulk runs above 200 bring it down to around $720 — that's for the 630A fixed type, though pricing scales with current rating and withdrawable configuration adds about 8-10%.
You've spec'd 12kV with 40kA breaking capacity, so we'd typically recommend the 275mm phase distance for better arc clearance, but 210mm works if your panel dimensions are tight — just check your existing busbar layout first.
It's basically the same breaker core that's been in KYN28 panels since 2010, so retrofitting is straightforward, though we've seen some buyers struggle with the contact stroke adjustment when switching from SF6 units (9±1mm is tighter than what they're used to).
One thing most buyers don't think to ask: teh energy-storage motor runs on either AC220 or DC220 by default, but we've had a guy request 110V for a retrofit and it added 3 weeks lead time, so confirm your control voltage early if it's non-standdard.
Mechanical endurance at 10,000 operations and electrcial at 20,000 is better than the typical 5,000 you'll see from older suppliers, though for frequent daily switching you'll want to keep an eye on over-travel tolerance of 3.5±0.5mm as it drifts after about 8,000 cycles.
So for the 200-unit RFQ on your desk, our company can ship in 35-45 days with full ISO9001 and CE docs, COAs per batch, and earthquake-resistant mounting brackets included — just send over your preferred phase distance and whether it's fixed or withdrawable.
We offer 150mm, 210mm, and 275mm phase distances. Standard 210mm is usually in stock; the other sizes may add a few days to lead time but no extra cost on the unit itself.
Yes, both ISO9001 and CE certificates are included with every order. We can also send them digitally before shipment if your compliance team needs them early.
MOQ is 5 units for any custom configuration, including the 3150A rating. For standard 630A or 1250A, we can do 2 units if needed.
Yes, we offer both fixed and withdrawable versions. Mechanical endurance stays at 10,000 operations regardless of the installation type.
Store it indoors in its original packaging, away from dust and moisture. It can handle up to 95% relative humidity daily, but keep it in a dry area with ambient temps between -10°C and +40°C.
