Basic Features

• Compact and economical overcurrent protection
• Directional and non-directional overcurrent protection with additional functions
• Detect intermittent ground faults and automatically block static measuring functions to avoid the flooding of messages and fault records
• Arc protection
• Protection from overvoltage and undervoltage
• Frequency and frequency change protection for load shedding applications
• Configurable power protection (active or reactive)
• Directional reactive power undervoltage protection (QU protection)
• Control with switchgear interlocking protection
• Extensive cybersecurity functionality (e.g. role-based access control (RBAC), protocolling security-related events, signed firmware or authenticated network access IEEE 802.1X)
• Reliable data transmission via PRP and HSR redundancy protocols
• Time synchronization using IEEE 1588
• Provides simple, quick and secure access to the device data via a standard Web browser to display all information, diagnostic data, vector diagrams, single-line diagrams, and device display pages
• Enables standard fault recording (buffer for a max. record time of approx. 40 sec. at 2 kHz)
