PV MCB

DC-Rated MCBs for Solar PV

PV MCBs give overcurrent protection on DC circuits up to 1000 V DC, with polarity-marked terminals and arc chutes designed for DC. This range stocks Chint NB1-63DC four-pole, C-curve breakers from 10 A to 63 A for solar and battery installations.

For higher-current DC protection see gPV fuses; for AC-side MCBs see Circuit Protection.
