So when a substation manager calls us about upgrading their 12kV switchgear, they usually start by asking about the handcart-style breaker—makes maintenance a lot quicker, and we've seen it cut downtime by roughly 40% in retrofit jobs, but it's not ideal for outdoor installations without extra enclosure protection.
Rated voltage options run form 3.6kV up to 12kV at 50Hz, with CB rated current choices spanning 630A to 3150A, and the cabinet matches those ratings pretty much across the board—the short-circuit withstand is 16kA to 50kA for 4 seconds, which is tighter than most budget gear we've tested, and the 1-minute power frequency withstand hits 42kV for higher votage models.
Actually, for power plants and indutrial mining setups, the IP4X shell and IP2X compartment door hold up well in dusty environments, though we don't recommend it for high-humidity coastal areas without additional ventilation—it's a fixed board design, not a withdrawable unit, so swapping modules takes a bit longer than some buyers expect.
We usually stock the 1250A and 2000A variants, lead time is about 20 days or so for standard orders, but check before you place a big one—MOQ is typically 5 units, and we include a COA with every batch.
You can choose from 3.6KV, 7.2KV, or 12KV depending on your grid requirements.
Yes, we have ISO9001:2000, VDE, and CCC certifications — we can share copies if you need them for your project.
Not exactly — the 50KA short-circuit opening current is available, but you'll need to match it with the right cabinet rated current; for example, it pairs with 3150A. We can help you spec it out.
We don’t have a strict MOQ for the KYN28-12, but typical wholesale orders start around 5 to 10 units. For smaller quantities, just let us know and we’ll see what we can do.
The standard shell is IP4X, which is fine for indoor substations. If you need it outdoors, we can customize the enclosure to a higher IP rating — just let us know your requirements.
