Complete motor protection relay is designed for safety and protection of large and medium scale induction motors.
MM30-W relay measures the real RMS values of neutral current, phase currents and line voltage.
It makes calculation of positive (ID) and negative (IS) components of phase current systems at the same time.
Its earth current inlet has active filter strained the 3. Harmonic.
