When you're retrofitting a 12kV switchgear lineup, most buyers we deal with are actually replacing older SF6 or oil-filled units, and they want something that drops straight into the existing cabinet without a major rework.
Even though the VS1-12/ZN63 is 12kV, the 3150A current rating with 31.5kA breaking capasity really matters in industiral plants where fault levels creep up over time — 25kA won't cut it if your transformer is getting oversized.
You'll get the full COA with every unit, and we usually ship within 20 business days or so, but if you need a faster turnaround on the 1250A variant, our company can often pull from stock.
The vacuum interrupter itself gives you about 20000 mechanicla operations before you'd even think about a check — that's pretty much double what a comparable SF6 breaker handles before the gas starts degrading.
It's not ideal for outdoor installations without an enclosure, but inside a temperture-controlled substation it's basically set-and-forget; the spring mechanism doesn't need the periodic maintenance a magnetic actuator does.
When you order, we include the CE and CCC certs in paperwork, and for the ISO9001 traceability, basically every componnet from the arc chamber to the contact springs gets a lot number on the SDS (usually 2-4 weeks for full batch documentation if you request it).
The 25kA rating is for systems with lower fault currents, while 31.5kA handles higher fault levels. Your choice depends on the fault current capacity at your installation point — check your grid’s short-circuit level or consult your electrical engineer.
We offer all standard ratings from 630A up to 3150A as listed. If you need a specific value not on that list, we can discuss it, but typically these cover most applications. Just confirm your requirement when ordering.
For 50 units, lead time is usually 4-6 weeks depending on current production load. Our MOQ is 10 units per order, but we can be flexible for first-time buyers or sample orders.
Yes, all three certificates are available and will be included with the shipment. We can also send digital copies in advance for your documentation or project approval.
Store it indoors in a dry, clean environment, away from dust and moisture, at -25°C to +55°C. If kept properly, it can be stored for up to 5 years before commissioning — just check the vacuum interrupter pressure before use.
