The label on a breaker shows LRL3640035M, but there is nothing in the literature indicating that is a good catalog number.
It is actually catalog number LAL3640035M. The LAL circuit breakers have been manufactured for many decades. During part of that time, the breaker labels were printed on a dot-matrix printer. Occasionally, during the printing process, a small portion of one or more letters would not be printed (see example photo). This can lead to the letters LAL appearing as "LRL". The bottom line is that we have never manufactured an LRL3640035M. In actuality, it is catalog number LAL3640035M.
