Low Voltage Circuit Breaker MCCB YRM3DC-320HU 2P

DC circuit breaker has overload long-time delay protection and short-circuit instantaneous protection functions. It is used to distribute electric energy and protect circuits and power supply equipment from  overload, short circuit and other dangers. The operating mechanism of the DC circuit breaker has the advantages of quick closing and quick reading of segments, compact structure, small size, and easy use.

YRM3-320 series photovoltaic dedicated DC plastic case circuit breaker is suitable for DC power grid circuits with rated voltage up to DC1500V and rated current 630A.

YRM3DC Photovoltaic DC Molded Case Circuit Breaker mainly relies on manual operation or electric closing, which complies with IEC IEC60947-2 standard. When the system fails, it can cooperate with the protection device and the automatic device to quickly cut off the fault current, prevent the accident from expanding, and ensure the safe operation of the system.
