Family features and characteristics
Drawout mounting
A drawout circuit breaker is used in combination with a cassette .
The cassette provides for all the required drawout features for
both primary and secondary connections . Mounting locations
for cassette mounted cell switches, primary safety shutters and
various key interlocks are part of the cassette design, to allow
for customized customer options . Refer to Section 11 for specific
drawout circuit breaker and cassette dimensions .
Cassettes – Available styles
Narrow frame Cassettes (for narrow frame and double
narrow frame breakers)
For narrow frame circuit breakers, there is one type of cassette
design, which uses horizontal stabs . Horizontal customer
busbar terminals are available (sold separately) . Optional bolt-on
90-degree adapters can be used to rotate the cassette’s primary
terminals to a vertical orientation as required .
Standard frame Cassettes (for standard frame and double
standard frame breakers)
For standard and double frame circuit breakers, there are three
cassette styles, all with vertical stabs available:
•
Basic Cassette with copper stabs
- This cassette comes with
factory installed copper stab/terminals on the cassette .
•
Basic Cassette without copper stabs
- The basic cassette
can also be ordered without factory supplied copper stab/
terminals . Ordering without stabs allows the switchgear
builder to integrate the cassette by using their vertical busbars .
