Asymmetry relay BA 9040, MK 9040N varimeter

• According to IEC 255, EN 60 255, VDE 0435 part 303
• Recognition of
    - voltage asymmetry
    - phase failure
    - voltage feedback
    - optionally with phase sequence recognition
• Optionally with adjustable response delay
• Insensitive against
    - symmetric harmonics up to K-factor K 20 %
• 2 LED displays for power supply and state of contact
• BA 9040: width 45 mm
    MK 9040N: width 22,5 mm

Applications
    Monitoring three-phase mains for voltage asymmetry, phase failure or incorrect phase sequence, e.g. in elevators, escalators, crane systems etc.
