MDK Density Switch

Application

SF₆ gas insulated RMU

SF₆ gas Insulated Switchgear

Features

Gas compensation ensures higher set point accuracy.

Micro switch enables normally open contacts and normally closed contacts freely switch to each other.  

High shock resistance

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