The frame module is matched to the ratings of the circuit breaker and permanently attached to the circuit breaker frame. It should not be removed or exchanged. The current sensors are internal to the circuit breaker frame and consist of two coils: one coil on an iron core and one coil on an air core (Rogowski coil).
It is difficult to know what is being meant by “frame” without additional information and context. The industry defines frame as the maximum current rating of a circuit breaker of a particular construction. Frame is also sometimes used to indicate the maximum setting possible for a particular circuit breaker.
