Monitors 3 phases (without NEUTRAL) with adjustable undervoltage level.

EAN: 8595188130134 (208V) | Code: 3710 (208V)
EAN: 8595188137119 (240V) | Code: 3711 (240V)

DESCRIPTION

  • Relay monitors phase sequence and failure (e.g. control of correct motor winding etc.).
  • Relay is designated for monitoring of 3-phase networks.
  • Supply from all phases which means that relay is functional also in case of one phase failure.
  • Supply and monitored supply Un:
    1-MODULE                                            3-MODULE 
    HRN-56/208 - 3x 208 V                      HRN-56/480 - 3x 480 V
    HRN-56/240 - 3x 240 V                      HRN-56/575 - 3x 575 V
    HRN-56/400 - 3x 400 V
  • Fixed time delay T1 (500 ms) and adjustable time delay T2 (0 -10 s).
