Embedded 2 voltage sensing capability for tie-point and renewable applications. Proven modular design rated for 10,000 full load operations. Hydrophobic Cycloaliphatic Epoxy insulation provides industry-leading reliability. Supply communication networks with DNP3 Level 2, Modbus, and IEC 61850. With 4 different setting groups, each is stored with individual setting values Main Function: • Fault detection(phase fault/ Earth fault/ SEF) • 3-stage over current protection (direction or non-directional) • — Fast and delayed TC Trip elements for phase and earth fault • — 50 type of built-in TC Curves (IEC , ANSI , Reclose curves) and 4 Customized TC Curves • — Define time HCT (High Current Trip) • Negative sequence over-current protection • SEF (Sensitive earth fault) detection • Cold load protection (Pick-up adjustment) • Magnetizing inrush restraints • Sequence coordinination, Single shot tripping • Open Line Detection & Phase Sync Fail Detexction (Va-Vr) • (Source-side & Load-side) • Auto Reclosing (Up to 5 Shots) • 4 setting groups, automatic setting group change depending on power flow
