VAMP 321 Arc flash protection system central unit

• Modular structure
  The design of VAMP 321 allows insertion of new hw to add performance and functionality to the system. The basic unit has two dedicated arc sensor inputs and is scalable from a standard to high-end arc flash protection system.

• PC configurable
  The system can be configured by the end-user with the VAMPSET software tool. Events and disturbance recordings are easily evaluated using a PC with USB connection.

• Event logs and disturbance recording
  First ever, Vamp introduces event and disturbance recorder in the arc protection system to enhance the pre- and after fault analysis of the arc phenomena.

• Compatible also with existing system
  The VAMP 321 relies on the same VAM I/O units, cabling and sensors as the companys other well-proven arc flash protection systems.

• Suits even for the most demanding environments (IP54)
  The new mechanical structure comprises a robust IP 54 -class HMI aluminium casing. Adjustable fixtures provide flexibile installation to every power system environment.

• Proven technology
  Developed in close cooperation with customers, the VAMP 321 combines the reliable technology of Vamps 50 and 200 series and that of the VAMP 221 arc flash protection system.
