AMVAC breaker

General overview

The AMVAC breaker is a magnetically actuated and latched
breaker capable of a high number of operations due to its
simplified design. Fully compliant with IEEE Standards C37.04,
C37.06 and C37.09, the AMVAC breaker is a great fit for many
applications.
Features
− Mechanical operations counter
− Optional roll-on-floor design
− Open, closed, ready/not ready lights and pushbuttons
− Maintenance-free magnetic actuator
