12/24kV medium-voltage switchgear is indoor metal-clad switchgear used to receive and distribute 3-phase AC 50Hz electric power with rated voltage of 12/24kV, and can provide control and protection of circuits. Various microprocessor-based relay protection units can be installed to achieve intelligent control, integrating functions of remote controlling, remote measuring, remote signaling and remote regulating. This medium-voltage switchgear can be configured with different types of vacuum circuits breakers or vacuum contactors.
