Appendix B.
Circuit Breaker Rejection Feature
General
In general, draw-out breakers of the same type and rating are
interchangeable in their equipment compartments; draw-out
breakers of different types or short circuit ratings are
intentionally made non-interchangeable. To prevent inserting
the wrong type breaker into a draw-out compartment, unique
“rejection hardware” is affixed to each breaker and its
cassette. The rejection is accomplished by pins on the sides
of the breaker and the blocks on the sides of the cassette.
Rejection Feature
This factory-installed, pin and gate device prevents the
insertion of a circuit breaker into a cassette if the nominal
rating of the breaker is incompatible with that of the cassette
and its ancillary equipment.
The information in the following appendices lists the available
rejection scheme combinations for the rejection feature.
AKD-20 AR rejection combinations are in Appendix C and
Entellisys AR rejection combinations are in Appendix D.
