1140 volt breakers

1140-volt breakers are high-voltage circuit breakers designed to interrupt electrical currents up to 1140 volts. These breakers are typically used in industrial, commercial, and utility applications where high-voltage electrical systems are present.

Here are some key characteristics and uses of 1140-volt breakers:

  1. Voltage rating: 1140 volts AC or DC
  2. Current rating: Typically ranges from 100 to 5000 amperes (A)
  3. Application: Industrial, commercial, and utility power distribution systems, including:
    • Power generation and transmission systems
    • Industrial power distribution systems
    • Commercial and institutional power distribution systems
    • Utility-scale power distribution systems
  4. Types: There are several types of 1140-volt breakers, including:
    • Air-break circuit breakers (ABCs)
    • Oil-filled circuit breakers (OFCBs)
    • Vacuum circuit breakers (VCBs)
    • Gas-insulated circuit breakers (GICBs)
  5. Features: 1140-volt breakers often have features such as:
    • High-voltage insulation and dielectric strength
    • High-temperature ratings
    • Low-maintenance designs
    • Remote operation and monitoring capabilities
