Voltage monitoring relay in 3P

3-wire, adjustable UV, phase failure/sequence, 3x208/240/400/480/575V

 

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
    • HRN-56/208 – 3x 208 V
    • HRN-56/240 – 3x 240 V
    • HRN-56/400 – 3x 400 V
  • 3-MODULE
    • HRN-56/480 – 3x 480 V
    • HRN-56/575 – 3x 575 V
• Fixed time delay T1 (500 ms) and adjustable time delay T2 (0 -10 s).
