Product Presentation


CRH9066 Series medium-voltage shore power connection distribution board is mainly used to connect cable winch and transformer. It is equipped with vacuum circuit breaker VCB, grounding switch, phase sequence indicator and other equipment, which can realize overcurrent protection and undervoltage / broken phase protection, and provide safety interlock function. Bank power connection distribution board is mainly used to connect shore power cable winch and transformer.



Product Features


1) Ship and shore maintain equipotential connection to reduce contact voltage, improve electricity safety, and provide safety interlock function.

2) Emergency cut-off. According to the need of the distribution board receives the emergency cut signal for switch operation.

3) Security interlocking function. Connector plug and socket interlock. The plug and socket are designed to control the shore electric circuit breaker to ensure the safety of the connection.
