Adding to its existing range of
switchgear interlocks, Fortress
Interlocks has worked with ABB to
develop one for use on the SACE
Emax circuit breaker. The Breaker
Lock forms part of a sequential
interlocking system that ensures the
safe operation of switchgear. Fortress
can supply interlocks to suit all makes
and model of switchgear.

The lock is constructed of zinc
alloy with stainless steel internal contact
surfaces.Heavy duty, it is suitable
for high frequency applications tested
to a million operations.

Fortress Breaker Locks offer
200,000+ non-masterable
combinations; although a limited
number of masterable locks is
available for some applications.
