YBRM5E-630 Series Electronic MCCB

YBRM5E-630 series electronic molded case circuit breakers are designed for medium to large current distribution systems with rated currents from 250A to 630A, providing high level of short circuit and overload protection for core distribution circuits and electrical equipment. The product is suitable for industrial and commercial power distribution environments within an altitude of 2000 meters, with a rated operating voltage of AC690V and below, and an insulation voltage of up to AC800V.The series has three breaking grades: N-type, H-type, and S-type. At 400V AC, the S-type breaking capability is excellent, with an ICU of up to 150kA, and ICS=100% ICUs, ensuring the continuity and high reliability of the power distribution system. Under AC690V conditions, the Icu breaking capacity also reaches 65kA (S-type). It supports thermal-magnetic (TM) or magnetic (MA) trip units, providing flexible long-delay setting and instantaneous trip protection up to 12 times in to accurately respond to v…
