Section 1: General information
IZM drawout circuit breakers come in a variety
of continuous current and interrupting ratings. To
prevent the insertion of a drawout circuit breaker
into a cassette with which it is incompatible,
rejection interlock key plates are provided for
both the circuit breaker and the cassette. As the
breaker is pushed into the cassette, the interlock
pins on the breaker move past the pins in the
cassette if they are compatible.
