Abstract
A molded case circuit breaker with interchangeable trip units has on its front face a frame protruding out from the front panel of the circuit breaker, and surrounding the circuit breaker operating handle. The frame has a window in which the end of a bracket support is inserted fixedly secured to the trip unit, when the latter is in place. An inscription, notably of the rating of the trip unit, is borne by a face of the bracket support so as to be visible at all times, even when a front protection plate covers the trip unit.
