Lock down tight
January 1st 2010 The Fortress Interlocks design team
has worked closely with ABB to
develop an interlock suitable for use
on the SACE Emax circuit breaker.
The lock is added to the existing
range of switchgear interlocks. The
lock is constructed of zinc alloy with
internal contact surfaces made of
stainless steel.
It is heavy duty and suitable for
high frequency applications, tested to
a million operations. Fortress
Breaker Locks offer in excess of
200,000 non-masterable
combinations; although a limited
number of masterable locks is
available for some applications.
The key moves the spindle
clockwise with smooth and effortless
rotation, and the key is freed at the
12 o'clock for ease of operation. A
spring-loaded stainless steel
dustcover is available as an extra. More articles from Fortress Interlocks Ltd: |
