Vamp Protection
  • Features

    Schneider Electric's VAMP 40 contains fixed hardware making it a standardised, user-friendly protection device, it also has a small form factor with limited installation depth, making it extremely adaptable to a variety of space limited applications. From measurement and primary circuit monitoring to communication functionality, the VAMP 40 encompasses much more than the standard protection functions of a traditional relay by replacing conventional metering functions. VAMP 40 is designed for distribution network overhead line feeders, cable feeders and motor feeders including large motors, capacitor banks and reactors. It supports a comprehensive set of industry standard communication protocols and is available with VAMP’s pioneering arc flash protection. Standard Manufacturers Warranty: 2 years


    • Comprehensive measurements
      A range of measurement functions including phase and residual currents, residual or line or phase voltage, frequency, current imbalance, maximum demand, negative phase sequence current, active and reactive power and energy according to the primary connection.
    • Power quality analysis
      Power quality analysis includes supervision of harmonics up to the 15th order, THD of currents and voltage as well as voltage sag and swell.
    • Full recording features
      Following a fault, the relay provides 200 event sequence recordings, fault value registration and disturbance recordings.
    • Ultra-fast arc protection
      The unique integrated arc fault functionality adds a new dimension to the total safety of the installation and the reliability of the protection and control system.
    • Extensive communication
      A large number of supported communication protocols are included in VAMP 40: IEC 60870-5-101, IEC 60870-5-103, Modbus TCP, Modbus RTU, Profibus DP, TCP/IP, SPA-bus, DNP 3.0 and IEC 61850.
    • User-friendly
      The free of charge VAMPSET software makes configuration, commissioning and operation user-friendly and ensures the protection and control needs of users are easily achieved. A wide auxiliary power supply, 19-265 V ac/dc, 50/60 makes this relay suitable for every kind of installation.
    • Slimline case
      Slimline casing ensures adaptability for a variety of settings where space is limited.


    Overhead line feeders, cable feeders, motor feeders, capacitor banks, reactors and busbars in power system distribution substations, power plants, industrial power systems, marine, offshore installations and space limited applications.
