SCM3DC-630D/2300 DC 2000V DC MCCB

The SCM3DC-630D series molded-case circuit breakers (hereinafter referred to as “the breaker”) are designed for use in high-voltage DC systems with a rated operational voltage up to 2,000 V and a rated operational current up to 630 A. They are intended for use in low-voltage networks to distribute electrical energy and to provide protection against overload, short circuit, and undervoltage in lines and equipment. The breaker can also be used for infrequent closing and opening of circuits under normal conditions as well as for infrequent starting of motors.
