MDK40 Density Switch

Application

SF₆ Gas Insulated RMU

SF₆ Gas Insulated Switchgear

Features

• Temperature compensation ensures higher set point accuracy.

• Can provide up to three sets of microswitch contacts allowing instant and accurate switching

• High shock resistance

• Normally closed contacts will not set a false alarm due to vibration
