Product Description

SRM3 DC Series

The SRMDC series molded case circuit breakers (hereinafter referred to as circuit breakers) are suitable for DC high - voltage systems. The rated operating voltage is up to 2000V, and the rated operating current is up to 630A and in lower - voltage circuits. They are used for short - circuit protection, and can protect the lines and equipment against overload, short - circuit, and undervoltage. They can also be used for infrequent closing and opening of lines under normal conditions and for the starting protection of motors.
