Appendix B. Circuit Breaker Rejection Feature

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.

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.
