Switchboards - Individually Mounted - AV-3 & PBII Switchboard

AV-3 & PBII Switchboard

GE's industrial-duty switchboard product lines Power Break® II and AV-3 Access*---feature individually-mounted breaker compartments for GE's complete product family of breakers.


Power Break II (PB) switchboards can house insulated case circuit breakers as mains, ties, and feeders; and low voltage power circuit breakers as mains and ties. AV-3 Access (AV3) provides individual compartments for molded case breakers serving as mains, ties, or feeders.


Both switchboards lines offer an outstanding cost effective, alternative to the more robust switchgear constructions. GE Switchboards feature:

  • Rugged construction - Specially designed bus structure enabling them to withstand the damaging effects of a short circuit for at least 30 cycles - a feature normally found only in switchgear.
  • Fast cycle times - GE has some of the fastest switchboard manufacturing cycle times in the industry.
  • Broad Functionality - Similar overall functionality to comparable ANSI-rated switchgear.
  • Multiple locations - GE has factories and Assembly Centers distributed throughout the world.
  • Cost effective design - GE Switchboard's save you money as functional alternative to switchgear.


Both switchboard product lines feature protective devices that can be provided with communications capability for connection to GE's Power Management Control System. Both switchboard lines also feature simple designs that allow for rapid field modification and maintenance - a must for use in applications where system downtime is absolutely unacceptable.
