Product Description
Swastik’s 11 kV Vacuum Circuit Breaker (VCB) Panel is an IEC 62271200 compliant, metalclad switchgear assembly engineered for safe, reliable mediumvoltage distribution in Indian industrial environments. Designed with internalarc considerations, robust busbar systems, and segregated compartments, it delivers high uptime, easier maintenance, and seamless integration with modern protection, metering, and SCADA systems.
* Voltage class: 12 kV, 50 Hz; shorttime withstand up to 25/31.5 kA for 1–3 s (projectspecific).
* Safety: internal arc options (IAC AFL/AFLR), pressure-relief ducting, visible-break earthing, key/mechanical interlocks.
*Construction: metal-clad PM partitions, Form-4 segregation, IP4X external and IP2X internal protection levels.
*Control and protection: vacuum breakers with racking/test positions, numerical relays (OCR/EF/SEF, BFR), event logs and time stamping.

FAQ'S
The 11 kV Vacuum Circuit Breaker panels are engineered to meet IEC 62271/200 requirements with options for Internal Arc Classification (IAC AFL/AFLR), verified IP protection levels, and documented routine/FAT testing for consultant and utility acceptance.
Typical configurations support 12 kV class systems with short-time withstand up to 25/31.5 kA for 1–3 seconds, coordinated with project fault levels; operating sequences and duty cycles are specified per application.
Panels use metal clad PM partitions with Form-4 segregation, pressure-relief paths, visible-break earthing switches, and mechanical/key interlocks, enabling safer isolation, test positions, and faster maintenance turnaround.
Yes. The solution supports numerical protection relays (OCR/EF/SEF, breaker-failure), multifunction energy meters, and seamless PLC/SCADA connectivity via common industrial protocols for alarms, logs, and remote control.
Each delivery includes GA, SLD, wiring schematics, nameplate schedules, and O&M manuals, along with routine test reports; support covers design review, FAT scheduling, commissioning assistance, and genuine spares for lifecycle reliability.
