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.
