We typically keep 30-50 units of these 11kv breakers ready to ship from our Shanghai warehouse, and larger orders of 33kv units need about 25 working days lead time. Packed in export-grade wooden crates, each one is strapped with steel bands and shrink-wrapped against moisture.
The rated current is 1250A for all three voltage options — 11kv, 22kv, or 33kv — and they’re fixed-mount with electric operation, 3-pole configuration. Breaking capasity isn't just a number; it's vacuum arc chamber that handles the job, with E2 electrical life and M2 mechanical class so you're not swapping units every few years. Most substation buyers go with the 33kv version for outdoor feeders, actually.
Overcurrent, overvoltage, and circuit-breaker failure protection come built into teh standerd unit, which is basically the common spec for utility-grade gear, we have ISO9001, CE, and CCC certificates on file — COAs can be attached to each shipment if requested. Not ideal for low-voltage distribution boards below 1kv, though; it’s overkill there.
A detail most buyers miss is that the 22kv variant runs slightly hotter in continuous duty — nothing dangerous, but factor it into your panel ventilation if running near the 1250A limit all day. Customizations like different terminal layouts or control voltage options (usually 110V or 220V AC) take an extra 2-3 weeks.
MOQ is 5 units for the 11kv, 2 units for 22kv or 33kv. Wire transfer or letter of credit accepted, and we do door-to-door on FOB terms — typical transit is about 30-35 days by sea, give or take waiting time for customs.
Our MOQ for these vacuum circuit breakers is typically 10 units, but we can negotiate for smaller orders if you're testing or have a specific project need.
For standard orders, lead time is around 20-30 days after payment and confirmation. Customizations may add a few extra days depending on the complexity.
Yes, we include all relevant certification documents—ISO9001, CE, and CCC—with each shipment as standard. Just let us know if you need any specific formats.
Absolutely, we can adjust the rated voltage to 11kv, 22kv, or 33kv on the same base model. Just specify your requirement when placing the order.
They come in export-standard wooden cases, which protect against moisture and impact during shipping. For long-term storage, keep them in a dry, indoor area away from dust and extreme temps.
