Monitors overcurrent
on measuring terminals
in 7 ranges

EAN: 8595188124928 (5A) | Code: 7040 (5A)
EAN: 8595188142885 (0,5A) | Code: 4288 (0,5A)

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
