2-6  Adapting cassette

Drawout circuit breaker cassettes are built and shipped in 
a “basic” configuration that can be adapted in the field to 
mate with specific circuit breakers. Specifically, the rejection 
interlock must be configured to the specific circuit breaker 
to be mated with the cassette, and the automatic secondary 
connections may have to be installed or upgraded. These 
operations are described in the following sections.

2-6.1  Rejection interlocks

Within any one physical frame size, the drawout circuit 
breakers come in a variety of continuous current and 
interruption ratings, some of which are incompatible with 
others. Double-wide circuit breakers also come with several 
phase sequence options that are also incompatible. To 
prevent the insertion of circuit breakers with (1) inadequate 
interrupting capability, (2) with physically incompatible 
primary disconnects, or (3) with an incompatible phase 
sequence, rejection interlock key plates are provided on 
both the circuit breaker and the cassette. The key plate 
on the circuit breaker is pre-assembled at the factory; but 
the cassette-side rejection plate and key pattern must be 
assembled and installed by the switchboard builder.

 CAUTION

Do not disable rejection interlocks. Doing so and using a 
lower capacity circuit breaker in an incompatible cassette 
could result in an electrical fault that could result in death, 
bodily injury, and/or equipment damage.

The rejection interlocks are steel pins in the floor of the cir-
cuit breaker cassette. As the circuit breaker is pushed into 
the structure, the mating pins on the bottom of the circuit 
breaker move past a set of corresponding pins in the cas-
sette if the circuit breaker and cassette are compatible. If the 
circuit breaker and the cassette are mismatched, the rejec-
tion pins will block the insertion of the circuit breaker into 
the cassette before the levering-in mechanism is engaged.

Before attempting to push the circuit breaker into the 
DISCONNECT position, compare the positioning of rejection 
interlock pins in the cassette with the information supplied 
on the circuit breaker’s nameplate. Proceed if the circuit 
breaker and the cassette are compatible.

2-6.2  Installing secondary jumpers

On drawout circuit breakers, the automatic secondary 
connector between the circuit breaker and the cassette can 
be ordered either fully populated or depopulated (without 
terminal blocks and jumper wires installed); these parts can 
be ordered separately and installed by the customer. If the 
necessary connections are not pre-installed, please contact 
an Eaton representative. These kits can also be used to add 
additional secondary wiring to upgrade circuit breakers in the 
field.
