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
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.
Voltage type: AC
Monitored levels: overcurrent
Monitored range: 0.5 - 25 A (50/60 Hz)
Output type: 1x CO, 8 A
Supply voltage (frequency): AC 230 V (50/60 Hz)
Dimensions: 90 x 17.6 x 64 mm (3.5˝ x 0.7˝ x 2.5˝)
