• Comprehensive library of hardware options, protection and control functions suitable to meet your system requirements
• The standard and user-programmable curves, supplemented by load blinders and voltage supervision offer fast and dependable fault tripping, without constraining circuit loadability
• Distance to fault location assists despatching of maintenance crews

Main characteristics:

• 4-stages of non-directional / directional overcurrent, earth fault, negative phase sequence overcurrent, sensitive earth fault protection
• 2-stage under/over voltage, 9-stage under/overfrequency, check synchronism, autoreclose and breaker fail are standard
• IEC 61850 redundant Ethernet, supporting self healing ring, RSTP, dual homing or PRP
• Graphical programmable scheme logic (PSL) eases protection scheme creation, and avoids the need for external logic controllers
• Hardware modularity extends upto a maximum of 48 binary (opto) inputs.
• Integrated functionality now permits control of up to eight switchgear elements in the bay, in addition to circuit breaker control.
