Current monitoring relay
PRI-52

Monitoring relay PRI-52 serves for monitoring of current level in 1-phase AC circuits

DESCRIPTION

  • 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... 
    -  changing over of appliances according to inverter‘s (converter) output by photocell applications
  • 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 600 A from external current transformer
  • slight setting (by potentiometer ) of tripping current - range AC 0.5.. 25 A
  • slight setting (by potentiometer) of delay - adjustable in range 0.5.. 10 s
  • supply voltage AC 230 V 
  • output contact 1x switching 8 A (AC1)
  • 1-phase version, 1-MODULE, mounting onto DIN rail, saddle terminals
