We've seen these units handle the full 3150A for years in industrial parks without a hiccup, and the 40kA breaking capacty is what most substation guys actually care about when a fault hits.
The 75kV lightning impulse withstand is pretty much the standdard for 12kV systems, so it matches most grid requirements you'd run into, but the 10,000 mechancial operations mean you're not swapping it out for a decade or so in normal use.
Opening speed sits at 0.9-1.2m/s and closing at 0.4-0.8m/s, which is tighter than some older models we've replaced—basically, it clears arcs faster without stressing the contacts.
For ordering, we usually stock the 630A and 1250A versions (check lead time on the 3150A), and you can pick fixed or withdrawable—most buyers go withdrawable for easier maintenance.
Phase distance varies form 150mm to 275mm depending on your switchgear panel, so measure that before you order—KYN28 cabinets typically use the 210mm spacing.
Anyway, the vacuum arc-extinguishing medium handles fault clearing without oil mess, and it's not suited for DC systems, just to be clear.
We typically require an MOQ of 10 units for the VS1-12, but we can negotiate smaller batches for first-time buyers or urgent projects.
For standard models with 630A or 1250A ratings, lead time is about 2-3 weeks. Custom configurations or non-standard phase distances might push it to 4-5 weeks.
Yes, absolutely. Each unit ships with ISO9001 and CE certificates, along with test reports for the vacuum interrupter and insulation resistance.
Sure. We offer phase distances of 150mm, 210mm, and 275mm. Just confirm the required distance when ordering, and we'll set it up accordingly.
Keep it indoors in a dry, clean environment with temperature between -25°C and 55°C. Avoid moisture and dust, and cycle the mechanical operations every 6 months to keep the contacts in good shape.
