Mechanical interlock
•
A family of mechanical interlocks are available to interlock the
closing of two or three Magnum breakers . The mechanical
interlock holds one or more breakers tripped (prevents closure)
when others are closed . A lever assembly is mounted on
each breaker, which interfaces with the pole shaft and the
tripper bar . The lever assemblies are interconnected with either
cables or rods, depending upon the relative orientation of the
breakers . Rods can be used only when the breakers to be
interlocked are vertically stacked . Cables can be used for any
orientation of the breakers . Mechanical interlocks are available
for both fixed and drawout breakers, and in both two-way and
three-way versions .
