Key Features
-
Comprehensive & Selective Protection Functions
- Overcurrent Protection (50/51, 50HS/51HS): Phase and sensitive ground time/instantaneous overcurrent protection with high‑set elements for fast fault clearing.
- Directional Overcurrent (67/67N): Enables selective coordination in ring main, parallel feeder, and networked systems.
- Earth Fault Protection (50G/51G, 50N/51N): Multiple setting groups for sensitive ground fault detection via residual current or dedicated CT inputs.
- Negative Sequence/Unbalance Protection (46): Shields motors and generators from overheating due to phase unbalance.
- Thermal Overload Protection (49): Provides cable thermal protection based on measured current.
- Under/Over Voltage (27/59) & Under/Over Frequency (81O/81U): Ensures system‑wide voltage and frequency stability.
- Automatic Reclosing (79): Configurable for multiple reclosing shots to restore service after temporary faults (critical for overhead lines).
-
Powerful Programmable Logic & Automation
- FlexLogic™ Programmable PLC: Allows custom control schemes and interlocking logic without additional hardware.
