Protection Relay Chint NJYB3-15
3-phase voltage relay with LED indicator
Protection:
• Phase failure
• Wrong phase sequence
• 3-phase voltage unbalance
• Over-voltage 380 - 460 V, Under-voltage 300 - 380 V
• Built-in microprocessor
• 3-phase 4-wire 220 V circuits with a frequency unbalance
(IEC 60947-5-1)
