We’ve been supplying these for medium-voltage switchgear projects, and basically what it does is protect transformers and feeders from short circuits and overloads inside indoor panels.
The 12kV rating handles most standdard distribution setups, and teh 20,000 mechancial cycles mean you’re not swapping it out every few years—opening time’s about 0.05 seconds at max voltage, give or take, and the contact stroke is 13±1mm (usually that’s tight enough for consistent arc suppression).
It’s better than older oil-based units for this kind of duty because the vacuum interrupter doesn’t degrade as fast, and we’ve seen these hold up well in substations with ambient temps ranging from -10°C to +40°C—mild opinion, but most buyers go with the 1250A rated current for industrial feeders.
Anyway, you’ll want to decide between fixed or withdrawable mounting—the withdrawable version is easier for maintenance, but it adds a bit to lead time (usually 20 days or so). Also, the operating voltage can be DC or AC at 110V or 220V, which covers most control circuits.
Not suited for outdoor exposure without an enclosure, as the IP rating is just for indoor panels, but our company can provide a weatherproof cabinet if needed—just confirm the MOQ when you’re ready.
The VS1-12 comes in three rated current options: 630A, 1250A, and 2500A, so you can pick the one that fits your load requirements.
Yes, it's certified under ISO9001, CE, and CCC, so it meets international quality and safety standards for electrical equipment.
We typically require a minimum order of 10 units for standard models, but we can discuss smaller quantities if you're testing the product.
Yes, it supports both fixed and withdrawable installation types, so you can choose based on your switchgear design and maintenance needs.
The mechanical life is rated at 20,000 operations, which means it's built for long-term, reliable use in demanding applications.
