Current monitoring relay of Imax level passing through a hole in 1P - AC PRI-52

Monitors the overcurrent of the conductor through the hole in the body of the device 

EAN: 8595188136556 | Code: 3655


  • Relay is designated for:
    - cistant device diagnostic (short circuit, take-off increasing)
    - preferred (priority) relay - two appliances (boiler and floor 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. 
  • 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 from external current transformer.
  • Slight setting (by potentiometer) of tripping current - range AC 0.5 to 25 A.
