DC MCB
DC miniature circuit breakers protect PV strings, battery circuits, DC distribution and telecom DC feeds against overload and short circuit, and give a resettable disconnect point in place of a fuse. Polarised and non-polarised versions are available; non-polarised DC MCBs are preferred in PV strings where reverse current can flow. LPES supplies 1P to 4P DC MCBs rated 250 V per pole (up to 1000 V DC in series) at 6 A to 63 A with C and K curves, tested to IEC 60947-2 and IS/IEC 60898-2, for combiner boxes, inverter DC inputs, BESS and telecom DC panels.
