SIPROTEC 4
What does SIPROTEC 4 mean?
SIPROTEC 4 is a new family of digital protection- and control-devices
All SIPROTEC 4 relays include control-functions and user-definable logic (PLC)
SIPROTEC 4 assists you with:
a simplified handling together with DIGSI 4
a better adaptation to local requirements
SIPROTEC 4 uses modern communication-technology for system integration
SIPROTEC 4 uses a common hardware platform
