Suntree DC MCB Circuit Breakers are protective switching devices designed for solar PV and other direct current electrical systems. They help protect DC circuits from overcurrent, short circuits, and overload faults while also allowing safe manual isolation during installation, maintenance, inspection, or emergency shutdown. This range includes 2-pole and 4-pole DC MCB options with different current and voltage ratings, making them suitable for solar panels, inverters, combiner boxes, batteries, charge controllers, and DC distribution boards.

Designed for Solar DC Protection

Solar systems generate direct current, so they require DC-rated breakers that can safely interrupt current flow when a fault occurs. Suntree DC MCBs are built for PV protection and are commonly installed between solar panels, combiner boxes, inverters, batteries, and other DC equipment. The available models include 20A, 32A, and 63A options, with voltage ratings such as 550V DC for 2-pole systems and 1000V DC for 4-pole systems. The 32A 550V 2-pole model is specifically described as suitable for protecting photovoltaic systems from overcurrent and short circuits. (Solar Shop Africa)
