Manufacturing for MOV has been discontinued.

The MOV is a digital multifunction protective relay that provides undervoltage, voltage absence, voltage presence, and closing and reclosing permission functions for two breakers. It offers a great flexibility of configuration for the definition of inputs, outputs and internal logics. The MOV includes analysis functions, such as event recording, oscillography recording, and an alarms panel.
