Current monitoring relay

1-phase, range 0.1-1/2/5/8/16A AC, adjustable delay

 

Description

 

• It serves for monitoring of heating in rail-switches, heating cables, consumption of 1-phase motors, indicates current flow.
• Flexible adjustment by potentiometer
• Adjustable delay 0.5 – 10 s to eliminate short current peaks.
• It is possible to use for current scanning from current transformer.
• Supply is galvanically separated from measured current, it must be in the same phase.
• Slight setting (by potentiometer ) of tripping current, choice from 8 ranges:
  • PRI-51/0.5A: AC 0.05 – 0.5 A
  • PRI-51/1A: AC 0.1 – 1 A
  • PRI-51/2A: AC 0.2 – 2 A
  • PRI-51/5A: AC 0.5 – 5 A
  • PRI-51/8A: AC 0.8 – 8 A
  • PRI-51/10A: AC 1 – 10A
  • PRI-51/0.1 – 10A: AC 0.1 – 10 A
  • PRI-51/16A: AC 1.6 – 16 A
