3-8.3 MECHANICAL ACCESSORIES
There are eight optional mechanical type accessories:
• Operations Counter
• Off Key Lock
• Cassette Lock
• Pushbutton Cover
• Prevent Close Cover
• Cassette Safety Shutters
• Cassette Cell Switch
• Door Escutcheon
• Waterproof Cover
• Mechanical Interlock
Operations Counter - The operations counter is a
mechanical device used to provide a record of the num-
ber of circuit operations. It is mounted in the lower right
portion of the circuit breaker and can be viewed through
the front cover (Figure 3-57).
Off Key Lock - The off key lock secures the circuit
breaker in the “OFF” position. It is mounted in the lower
right portion of the circuit breaker and can be viewed
through the front cover (Figure 3-57). The customer
supplies the key lock. The provisions available are for
Kirk, Castell or Ronis.
Cassette Lock - A cassette mounted lock can be used
in conjunction with different interlocking schemes (such
as main-tie-main) (Figure 3-58). The lock holds the cir-
cuit breaker trip-free in the connected position, prevent-
ing it from being closed.
Up to three lock cylinders can be installed on one cas-
sette. Cutler-Hammer supplies the lock provisions only.
The customer is responsible for the locks, which can be
Kirk or Castell.
Pushbutton Cover - Padlockable covers are available
to limit access to the “ON” and “OFF” pushbuttons
(Figure 3-59). They can be installed with either or both
pushbutton covers in place.
Prevent Close Cover - All access to the “ON” pushbut-
ton can be prevented by adding the fixed Prevent Close
Cover to the pushbutton cover.
Lockout Cover - When padlocked, it maintains the
“OFF” button in the actuated position which prevents
closure of the breaker.
