摘要： An industrial-rated circuit breaker cover is adapted for optimally receiving an advanced electronic trip unit including a keypad and display unit as well as a basic electronic trip unit providing circuit interruption facility without the keypad and display unit. The load terminals electrically connect the current sensing transformers with the external power circuit and receive the same size lugs that connect the circuit breaker with the electrical power distribution circuits.
