Frequently Asked QuestionsWhy did we change the miniature circuit breakers?The new MCBs offer increased mechanical operating life, higher current ratings and a uniquedual-terminal design that provides better connection of multiple conductors (bus bar andwire). In addition, there are more options for accessories, including an innovative auxiliarycontact that mounts at the bottom of the 1492-SPM, 1492-D and 188-J, -K requiring noadditional DIN Rail space.Are the new breakers similar in size?Yes, the new breakers are equal in pole width to the old and have only minor variations inheight and depth.Can I mix new breakers with existing breakers?Yes, although bus bar compatibility, if used, must be evaluated.Can I use the same bus bars as before?The 1489-M and 188-J, -K products require the use of a new bus bar series. The 1492-SPM and1492-D bus bars are unchanged. In both cases, it will not be possible to connect old and newbreakers with the same bus bar.Can I use the same accessories?These are newly designed breakers and must be used with the new offering of accessories.Most of the new accessories are right side mounted.11 Miniature Circuit Breaker Migration
