Noark DC 32 Amp 4Pole 1000VDC Dinrail Circuit Breaker

A DC circuit breaker is an OCPD that protects electrical devices operating with DC and contains additional arc-extinguishing measures. DC circuit breakers are a relatively new technology to most homeowners since most devices used in a house work with AC and AC circuit breakers. General AC circuit breakers for the home are rated to interrupt above 6 kA. Some manufacturers produce circuit breakers that are dual-rated for both AC/DC from 48 VDC to 125 VDC. DC circuit breakers are used with 24 VDC to 48 VDC programmable logic controllers (PLCs) and in wind power applications.
