Operations Counter - The operations counter is a
standard mechanical device used to provide a record
of the number of circuit breaker operations. It is
mounted on the right side of the circuit breaker and
can be viewed through the front cover (Figure
3-10).
OFF Key Lock - The key lock secures the circuit
breaker in the "OFF" (open) position. It is an
optional device mounted in the lower right portion
of the circuit breaker and can be viewed through
the front cover (Figure
5-8). The customer supplies
the key lock. The lock choices are Ronis, Castell or
Kirk.
Mechanical Interlock - A family of mechanical
interlocks are available to interlock the closing of two or
three circuit breakers. The mechanical interlock holds
one or more circuit breakers tripped (prevents closure)
Figure 5-27 Pushbutton Cover Mounted
is interconnected with either cables or rods, depending
upon the relative orientation of the breakers. Rods can
be used only when the circuit 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 circuit breakers and
in both 2-way and 3-way versions. An illustration of a 2-
way cable interlock mounted on two drawout circuit
breakers is shown in Figure
5-9.
Pushbutton Cover -
An optional padlockable cover is
available to limit access to the "ON" and "OFF"
pushbuttons (Figure
5-27).
Prevent Close Cover - The optional prevent close cover
completely prevents access to the "ON" pushbutton. It
must be used in conjunction with the pushbutton cover.
Door Escutcheon - The door escutcheon is an optional
molded frame used to seal space between the circuit
breaker and a compartment door cutout, should the
customer choose to have a through the door type
mounting configuration. It is supplied with a mounting
gasket (Figure
5-28).
