We've been running these in distribution substations for about a year now, and spring mechanism cycles reliably even after thousands of operations—it's basically a workhorse for 40.5kV systems.
Withdrawable design makes maintenance pretty straightforward, and the 2000A continuous rating handles heavy indutrial loads without sweating, though it's not ideal for outdoor installations above 1000m altitude.
The vacuum interrupter handles 31.5kA fault currents cleanly, and the mechancial life is rated at 10000 operations or so, which is better than most oil-based breakers we've dealt with.
Space is tight in most retrofits, so the 1300×500×1750mm footprint actually fits into existing cubicles without major modifications, and the spring mechanism eliminates hydraulic leaks.
MOQ is typically 3 units, COA included with every shipment, and we usually have stock on the 2000A version—confirm lead time for teh 31.5kA variant.
Our standard MOQ is 2 units for this model, but we can discuss single-unit orders depending on stock availability.
Lead time is usually 25-35 working days after order confirmation, but we can expedite to 15 days for urgent orders with a small surcharge.
Yes, we provide ISO9001, CE, and CCC certificates with each shipment. The test reports and compliance documents are included in the technical file package.
Absolutely. The 2000A rated current is for normal load operation, while the 31.5KA breaking capacity is the maximum short-circuit current it can safely interrupt. Both specs are independently tested and certified.
Store it in a clean, dry indoor area with temperature between -15°C and +40°C and humidity below 95%. Keep it in its original packaging to avoid dust and moisture damage.
