Relay monitors phase sequence and failure ( e.g monitoring of correct motor winding etc.) in 3 phaze main

EAN: 8595188137225 | Code: 7512

DESCRIPTION

Relay monitors phase sequence and failure, exceeding of monitored voltage in 3-phase main.
HRN-55: supply from all phases, which means that function of relay is applicable also if 1-phase fails.
HRN-55N: supply L1, L2, L3-N, it means that relay also monitors break of neutral point.
Fixed delay T1 (500 ms) and adjustable delay T2 (0.1 - 10 s).
