We went with this vacuum circuit breaker mainly because of that it hits the CE and RoHS marks cleanly, which takes teh headache out of importing into the EU region especially—customs usually just nods through when those docs are in order, saving us about three weeks of back-and-forth on paperwork.
The arc-extinguishing medium being vacuum rather than SF6 or oil means it quenches arcs much faster in high-voltge fault conditions, and with 12500 operations at that speed you're not swapping units every maintenance cycle; the silver-plated copper contacts handle frequent switching pretty much without degradation.
Dimensions are 73×72×80mm, which is a lot smaller than the previous drawout breakers we were sourcing—that dropped our cabinet costs by roughly 15% since our company can fit more units per panelboard layout now.
Origin form China is fine here because the COA came with every batch and we already knew the supplier's QC tolerances hold to under 0.5% defect rate over the last three orders, plus the RoHS cert specifically covers the solder alloys used in control board.
730-5 electrcial operation type, so if your project needs manual override you'll want to spec in a separate disconnect switch—it's not designed for that, but for permanent substation installations where remote tripping is the norm it's actually better than most available options.
Lead times usually run 30 days or so, but we confirmed 28 on this batch because the order was placed before Q4 seasonal crunch; one thing I'd flag is the silver-plated copper spec means higher conductivity but you get micro-pitting after about 4000 cycles in dusty environments, so if your site has high particulate load that's worth planning for.
The MOQ is 10 units, but we can arrange a sample order of 1-2 pieces for testing. Just let us know if you need that.
Lead time is usually 15-20 working days for standard orders. If you need it faster, we can expedite for a small fee.
Yes, we include CE and RoHS certificates with every order. You'll get them in the shipping package or via email if requested.
Standard contact material is silver-plated copper, and dimensions are fixed at 73×72×80mm. Customization on those specs isn't available, but we can adjust the drawout/insert installation if needed.
Store it in a dry, clean environment with temperatures between -25°C and 55°C. It'll last about 5 years in storage without performance loss.
