  • Durable & Long-Lasting: Built with high-quality components to withstand demanding industrial environments and provide extended operational life.

Technical Specifications (Examples – you would need to verify these specific values with ABB’s datasheets):

  • Rated Voltage: (e.g., 72.5 kV, 145 kV, 245 kV) – Crucial for search queries.
  • Rated Current: (e.g., 2000 A, 3150 A, 4000 A) – Important for capacity matching.
  • Rated Short-Circuit Breaking Current: (e.g., 40 kA, 50 kA, 63 kA) – Indicates fault handling capability.
  • Insulation Type: (e.g., SF6 gas-insulated, vacuum-insulated, air-insulated) – Key technical differentiator.
  • Operating Mechanism: (e.g., Spring-operated, Hydraulic-operated, Pneumatic-operated) – Details how the breaker functions.
  • Breaking Time: (e.g., < 3 cycles, < 50 ms) – Speed of operation, vital for fault clearing.
  • Operating Temperature Range: (e.g., -40°C to +55°C) – Environmental resilience.
  • Standards Compliance: (e.g., IEC 62271-1, IEEE C37.04) – Demonstrates adherence to industry safety and performance standards.
  • Application Environment: (e.g., Indoor/Outdoor substations, industrial plants, renewable energy sites) – Helps users identify suitability.
  • Maintenance Interval: (e.g., Low-maintenance design, typically 5-10 years) – Highlights operational cost benefits.
  • Dimensions & Weight: (e.g., L x W x H in mm, Weight in kg) – Important for planning and logistics.
  • Communication Protocols: (e.g., IEC 61850, Modbus RTU) – If it has advanced monitoring, this is relevant for smart grids.

Target Applications:

  • Utility Substations: Essential for transmission and distribution networks.
  • Industrial Facilities: Critical for power management in heavy industries like manufacturing, mining, and chemical plants.
  • Renewable Energy Grid Connections: Integrating solar and wind farms into the main grid.
  • Data Centers: Ensuring reliable power supply and protection for critical IT infrastructure.
  • Railway Electrification: Providing power switching and protection for rail networks.
