Standard Indicators include:
• The breaker status indicator shows the condition of the main
contacts (OPEN, CLOSED).
• The status of the closing springs is indicated as CHARGED or
DISCHARGED.
• The draw-out position indicator displays whether the breaker is
in the CONNECT, TEST or DISCONNECT position.
• The breaker also includes a switch that provides main contact
status indication to the POWER LEADER™ Power Management
System.
• The optional Reduced Energy Let-Through (RELT) is provided
with an ON/OFF contact closure to positively indicate whether the
RELT setting is enabled or not.
A factory-installed rejection feature prevents mismatching
breakers and cassettes/substructures. This prevents (a) inserting
a breaker with a lower interrupting rating into a higher rated
cassette/substructure and (b) inserting a higher current rated
breaker into a lower rated cassette/substructure.
The breaker racking mechanism is accessible through the front of
the cassette and permits safely disconnecting/withdrawing the
circuit breaker without opening the door and exposing personnel
to live parts during the process.
The padlocking device is standard on breakers and allows up to
three padlocks with 1/4" to 3/8" diameter shanks to secure the
breaker in the OPEN/TRIP FREE position. A padlock provision on
the front panel of the cassette/substructure permits locking
access to the racking screw. Racking access can be locked with
the breaker in the CONNECT, TEST, DISCONNECT position with up
to three padlocks.
Up to four optional key interlocks are available (Kirk, Ronis,
Profalux, Castell). Switchgear applications utilize a Kirk key
interlock mounted in the cassette. A maximum of two key
interlocks may fit in the cassette.
Optional lockable shutters are available (factory installed).
This optional cassette/substructure device permits local or
remote indication of the circuit breaker status (CONNECTED, TEST,
DISCONNECTED), 2NO/2NC single pole, double throw contacts are
available for each position.
Optional Lifting Beams/bars with separate slings are available for
all breaker sizes. A Universal Lifting Beam is also available
capable of lifting a 3 Pole Envelope 1
Optional IP54 covers (protects against harmful amounts of dust
and splashing water) are available for all breaker sizes.
