Abstract
A molded case multi-pole circuit breaker having an electronic trip unit to determine overcurrent conditions connects with a corresponding current transformer within each pole to sample circuit current. Upon the occurrence of an overcurrent condition, a trip actuator is energized to interrupt the circuit current. A current transformer adapter unit supports the trip actuator wire conductors and pin connectors while at the same time shielding the current transformers from the circuit breaker exhaust gases.
