LINETRAXX® VMD460-NA

Product catalog summary

Product Description
The LINETRAXX® VMD460-NA is designed for network and system protection, specifically for monitoring network feed-in from generating plants. It ensures protection by disconnecting the network and plant during inadmissible operating states, adhering to single-fault tolerance principles. The device supports coupling of generating plants to the network when conditions are met, guided by country-specific standards stored as selectable programs.

Application Examples

Central NS protection (VDE-AR-N 4105)
Protective disconnection (VDE-AR-N 4110, BDEW)
Interface Protection (IP) (EREC G99, G59, G83)
Automatic disconnection for generating plants parallel to the network

Functional Description
The VMD460-NA disconnects the network when protective or monitoring functions are triggered. It includes voltage and frequency protection, islanding detection, unbalance detection, and remote trip capabilities. The device also features a test function for checking circuits and switches, and an automatic self-test.

Device Features

Monitoring of 1AC, 3AC, 3NAC systems
Continuous phase and line-to-line voltage monitoring
Reconnection after short interruptions
Voltage and frequency protection functions
Islanding detection and unbalance detection
Remote trip and test functions
Password protection and factory reset
History memory for 300 faults
Remote configuration and maintenance
Backlit graphic LC display

Standards and Certifications
The device complies with various standards including VDE-AR-N 4105, VDE-AR-N 4110, BDEW, CEI 0-21, and others. It is certified under UL File No. E173157.

Technical Data
The VMD460-NA operates with a nominal supply voltage of AC/DC 100-240 V and supports a range of system voltages and frequencies. It features a history memory, password protection, and supports remote configuration. The device is designed for continuous operation and can be mounted in any position.

Wiring and Connection
The document provides detailed wiring diagrams for different standards (VDE-AR-N 4105, VDE-AR-N 4110, CEI 0-21) and outlines connection types, including screw-type and push-wire terminals.

Environmental and Mechanical Conditions
The device operates within a temperature range of -25 to +55 °C and is classified under various climatic and mechanical conditions according to IEC standards. It is housed in a polycarbonate enclosure with a flammability class of UL94 V-0.
