Direct Current (DC) Circuit Breakers

Motor Circuit Protection

DC Molded Case Circuit Breakers are ideal for energy storage, transportation, and industrial DC circuits. They are also used in ungrounded battery supply circuits for emergency back-up and standby power. Available up to 150A, 750 VDC and up to 2000A, 600 VDC. For DC breakers used in grounded photovoltaic systems in solar installations, application engineering and review ensures protection requirements are met.
