80A Din Rail Breakers

serge74serge74 Registered Users Posts: 7
Has anyone here heard of a 80A din rail breaker that is UL listed for 24V? I found a SQD breaker that could possibly fit the bill but I am uncertain if it is really UL listed for 24V. It does say that it is listed for 48V but it doesn’t mention anything about 24V. Any ideas?

    the qo and qou type breakers are rated to 48v, but i don't see an 80a version.

    And the rating is for 48 volt DC Maximum... Lower voltage use is fine (within the current rating).

    You might try Midnite Solar. They have an extensive selection of din rail breakers. Although 80 Amps DC is a bit stout. They may have a source, or something for a product in development. good Luck Vic
