Introduction
The BR-AC30D and BR-AC60S are AC breakers that are used as the disconnect
switch and overcurrent protection device for the inverter’s AC input. These
circuit breakers come equipped with slots in the molded case for attaching
mounting brackets/feet, which allows them to be easily back-mounted to the
breaker mounting plate inside the MP (Magnum Panel) enclosure.
Depending on the part number, the breaker is either a 30 amp dual pole
(PN: BR-AC30D) or a 60 amp single pole (PN: BR-AC60S), general purpose
Square-D QOU™ type, back-mountable, AC circuit breaker.
