Operations counter
The operations counter is a mechanical device used to
provide a record of the number of circuit operations. It is
mounted in the lower right portion of the breaker and can
be viewed through the front cover. The counter increments
by one once the spring is fully discharged and the breaker
is closed.
Off key lock
The off key lock secures the breaker in the OFF position.
It is mounted in the lower right portion of the breaker and
can be viewed through the front cover. Eaton supplies the
lock provisions only. The customer supplies the keylock.
The provisions available are for Kirk, Castell, Ronis, or CES.
Cassette lock
A cassette-mounted lock can be used in conjunction with
different interlocking schemes, such as main-tie-main. The
lock holds the breaker open in the CONNECTED position,
preventing it from being closed. Up to three lock cylinders
can be installed on one cassette. Eaton supplies the lock
provisions only. The customer is responsible for the locks,
which can be Kirk or Castell.
Pushbutton and prevent close cover
Padlockable pushbutton covers are available to limit
access to the CLOSE and OPEN pushbuttons. They
can be installed to cover only one pushbutton or both
pushbuttons. All access to the CLOSE pushbutton can be
prevented by adding the fixed prevent close cover to the
pushbutton cover. This cover is included in the pushbutton
cover kits.
