It isn't really built for high-cycle frequent switching if you're doing multiple operations per day—the electrical life tops out at 100 full load breaks, so most buyers know this better for long-term protection rather than daily on-off use.
That said, for a distribution feeder or substation outgoing line, it's pretty much perfect since the vacuum arc-extinguishing cuts erosion nicely, and mechanicla life holds up for 10,000 operations give or take across years of standby service.
We've shipped these at 11kV, 22kV, and 33kV with 1250A continuous rating and a 31.5kA short-circuit breaking capasity, spring-charged mechanism, fixed three-pole mount, all built to IEC 62271-100 standerds (usually 2-4 weeks lead time).
Also packs overcurrent and short circuit protection functions built right in—no separate relay box to wire up—and works fine form -25°C up to 40°C, though above 1000m altitude you lose a bit of insulation margin so just flag your site if that's the case.
One thing you'll want to know: teh 150kg weight means two people on install, and we typically ship with an outdoor-rated enamel coating, but if you need extra corrosion resistance for coastal zones just mention it on the order.
We typically require a MOQ of 5 units for this model, but we can discuss smaller orders depending on stock availability.
Yes, we include IEC 62271-100 and CE compliance certificates with every unit. GB certification is also available if needed.
Yes, the 31.5kA breaking capacity applies across all voltage ratings—11kV, 22kV, and 33kV—so it's consistent for your system.
Lead time is usually around 25-30 business days after order confirmation, but we can prioritize urgent requests if needed.
Store it in a clean, dry place within -25°C to +40°C, with relative humidity below 95%. Keep it indoors and away from corrosive gases to maintain the vacuum interrupter's condition.
