PRI-52:Monitoring current relay

  • relay is designated for:
  • - distant device diagnostic (short circuit, take-off increasing)
  • - preferred (priority) relay – two appliances (boiler and fl oor heating) operating on one phase, but never run together – prevention against current overload and circuit breaker tripping. Enables to save your main breaker expenses.
  • - current tranzit indicator – informs about heating activation, ceramic hob, ventilator…
  • NEW – hole for threaded conductor passes through the body of device
  • part of device is current transformer, which is sensing size of current in threaded conductor
  • possible to use also for sensing of current up to 600A from external current transformer
  • slight setting (by potentiometer ) of tripping current – range AC 0.5….25A
  • slight setting (by potentiometer) of delay – adjustable in range 0.5…..10s
  • supply voltage AC 230V
  • output contact 1x switching 8A (AC1)
  • 1-phase version, 1-MODULE, mounting onto DIN rail, saddle terminals
