Phase Sequence Module
OA 9059

The phase sequence relay OA 9059 of the VARIMETER series, for installation in the motor terminal box, monitor compliance with the correct phase sequence L1 - L2 - L3 and the presence of the three phase voltages in a three-phase system.

Advantages
. Protects mobile equipment against damage or destruction coming from wrong phase sequence
. Reduced wiring by mounting directly in the motor connection box
