Double Pole Magnetic
AC Circuit Breakers
•The industry standard circuit breaker for Blue Sea Systems’ electrical panels
•Used as AC main circuit breakers to switch both hot and neutral legs
•With neutral circuit on one pole and hot circuit on other pole, both poles will
trip if either pole trips
•Combines switching and circuit protection into a single device
•B-Series circuit breakers are Emarked
