Electronic control board
The electronic control board technology for the AMVAC breaker
provides improved reliability due to its self-monitoring functions
and features. Featuring coil monitoring, sensor monitoring,
optional under-voltage trip and optional energy failure trip, the
AMVAC breaker is customizable for any application.
By managing the 45 ms current limited pulse delivered to the
mechanism by the on-board capacitors, the electronic control
board eliminates one cause of common failures in typical spring
mechanism breakers – the burning of trip and close coils.
Breaker racking truck
ABB’s breaker racking truck for switchgear is integral to the
breaker itself in lieu of being inside the switchgear breaker cell.
Rated for 180 foot-pounds of torque, the breaker racking truck
exceeds the industry standard of 50-60 foot-pounds by a factor
of three, greatly reducing the possibility of an over-torque con-
dition.
The breaker racking truck is rated for 1000 rack in-rack out
operations, exceeding the ANSI Standard of 500 operations.
