Frame size

"A term designating a group of circuit breakers, the external physical dimensions of which are common to a range of current ratings. Frame size is expressed in amperes corresponding to the highest current rating of the group. Within a frame size, the width may vary according to the number of poles. This definition does not imply dimensional standardization."
PowerPact circuit breakers are available in seven frame sizes covering 125 A, 150 A, 250 A, 600 A, 800 A, 1200 A, and 3000 A.
