Direct current miniature circuit breakers

A new line of direct current (DC) miniature circuit breakers (MCBs), specifically designed for higher voltage applications with DC currents. The new line of Series 1110 DC MCBs feature an industry-best rating of 250V DC per-pole, far greater than the highest per-pole ratings currently available from comparable DC MCBs, which top out at 125V DC.

Available in one- to four-pole constructions for circuit protection up to 1000V DC, with current ratings from 0.5A to 63A, the robust devices provide the most efficient short circuit and overload protection available, affording end-users significant cost, space and time savings. They are UL 489B listed for photovoltaic renewable energy system applications. Additional target applications include EV charging stations, energy transmission and distribution networks and industrial control, such as powering the large motors used in robotic, automation and material conveyance installations.
