Configuration-led support for indoor VS1 vacuum circuit breakers. Start with the switchgear arrangement, operating requirement, and available project documentation before confirming a configuration.
This image-backed VS1 breaker path organizes the available product evidence for project review. Final electrical, mechanical, and interface values remain project-confirmed.
Rated values and dimensional information for the withdrawable indoor vacuum circuit breaker.
| Review item | Rated value or project confirmation requirement |
|---|---|
| Configuration | VS1-12 indoor three-phase AC vacuum circuit breaker |
| Rated voltage / frequency | 12 kV / 50 Hz |
| Power-frequency withstand voltage (1 min) | 42 / 48 kV – confirm the applicable insulation condition |
| Lightning impulse withstand voltage (peak) | 75 / 85 kV – confirm the applicable insulation condition |
| Rated current options | 630 / 1250 / 1600 / 2000 / 2500 A |
| Short-circuit breaking / short-time current | 20 / 25 / 31.5 / 40 kA |
| Peak breaking / making current | 50 / 63 / 80 / 100 kA |
| Rated short-circuit duration | 4 s |
| Secondary-circuit withstand voltage (1 min) | 2000 V |
| Rated operating sequence | O – 0.3 s – CO – 180 s – CO |
| Control-voltage options | DC110 / DC220 / AC110 / AC220 V – confirm the selected mechanism |
| Mechanical life | Project confirmation required; source values conflict and are not published here |
The listed parameters apply only to the VS1-12 configuration shown. Mechanical life remains project-confirmed because the source material contains conflicting values. The dimension callouts are view-specific labels: 681, 652, 638, 598, 508, 433, 280, 275, 200, 89, 77, and 40 mm are shown across the front and side views. They are not one overall W x D x H declaration. Confirm the selected truck/frame, switchgear cabinet interface, pole spacing, mounting holes, and all project interfaces before quotation or production.
Product construction, typical switchgear use, and the key interface checks required before a VS1-12 configuration is confirmed.
The breaker body can be combined with a propulsion mechanism to form a withdrawable handcart unit for indoor metal-clad switchgear.
Confirm the closing and tripping control voltage, motor/manual charging arrangement, auxiliary contacts, and applicable mechanical or electrical interlocks.
Use the selected VS1 configuration for protection and control duties in 12 kV distribution switchgear, including feeder and transformer applications.
Confirm the truck frame, primary contact interface, pole spacing, available clearances, and interlocking scheme.
Match voltage, current, insulation level, short-circuit duty, and operating sequence to the selected project requirement.
Confirm the selected control voltage, terminal wiring, auxiliary contacts, and required protection or monitoring interface.
Use the published VS1-12 data with the selected switchgear interface and project documentation. Final configuration items remain subject to project review.
The table and dimensional drawing apply to the VS1-12 withdrawable indoor configuration at 12 kV / 50 Hz. Do not apply them to a fixed installation or another voltage family without the corresponding project evidence.
No. The drawing uses view-specific labels across the front and side views. Confirm the selected truck frame, panel interface, pole spacing, mounting holes, and available clearances for the project.
Select rated current, short-circuit duty, insulation condition, and control voltage against the project requirement. The listed values show the available VS1-12 review range, not one universally applicable order configuration.
Provide the switchgear layout, primary-contact interface, mounting arrangement, control-circuit requirement, available drawings or nameplate photos, quantity, and operating conditions.
Start the technical review with the selected rating, withdrawable truck and cabinet interface, and control-circuit requirements for the intended switchgear application.
