Circuit Protection Breakers

General circuit protection breakers for safeguarding wiring and equipment from overloads and short circuits in marine electrical systems. This broader breaker selection spans different operating formats and protection duties, from DC accessory circuits to AC equipment feeders. Start with voltage, available fault current, conductor size, load characteristics and required approvals; then choose thermal, hydraulic-magnetic or molded-case construction. A breaker that physically fits the panel is not necessarily an electrically correct replacement.
