Compact Air-Insulated Breaker Assembly CABA

Compact switchgear

GE’s Compact Air-Insulated Breaker Assembly (CABA) is a modular, compact switchgear system combining a live tank circuit breaker, double sided disconnect switch and other AIS equipment mounted on a common frame. It can be installed in greenfield substations or retrofit into an existing substation. CABA can be installed on existing foundations and is designed for space savings due to its compactness.

This flexible, compact breaker assembly is well suited for a variety of applications including transformer protection, line and cable switching, capacitor bank and back-to-back switching, reactor switching and circuit switching.

GE Advantage

CABA leverages GE’s expertise in high voltage equipment, including circuit breakers and disconnect switches, to provide a reliable substation solution. GE has more than 100,00 circuit breakers with spring-spring operating mechanisms in service throughout the world.

Key Features

  • Complete factory assembly allows CABA to easily replace existing equipment for a high quality solution with reduced delivery time
  • Ideal for replacement or upgrade of circuit switcher installations providing full circuit breaker function in the same space
  • Reliable spring-spring operating mechanisms
  • Meets the requirements of IEC and IEEE/ANSI standards

Key Benefits

  • Modular design for green field or retrofit installations
  • Improved substation protection
  • No new foundations needed for retrofits with standardized modules
  • Easy installation and commissioning
  • Circuit breaker performance in a circuit switcher footprint
