Multifunction current monitoring relay in 1P - AC - PRI-34
It is used to monitor the value of alternating current in, e.g.: motors, heating cables, illumination and other devices
Undercurrent monitoring relay in 1P - AC by external CT - PRI-35
Protects the pump motor (submersible pump) against no-load operation with ext. current transformer. The power supply is not galvanically separated from the monitored current terminals. Terminals A2, B2 are internally connected
Current monitoring relay of Imin and Imax in 1P - AC/DC PRI-41
Used to monitor overloading / relief (machine, motor, etc.), check consumption, diagnostics on a remote device (burning, short circuit, increased current draw, etc.).
Current monitoring relay of Imax level passing through a hole in 1P - AC PRI-52
Monitoring relay PRI-52 serves for monitoring of current level in 1-phase AC circuits
Current monitoring relay of Imax level in 1P - AC PRI-51
Serves for monitoring of heating in rail-switches, heating cables, consumption of one-phase motors, indicates current flow
Current monitoring relay of Imax level passing through a hole in 1P - AC PRI-32
Current transformer is a part of the product. Inside this transformer there is a wire which senses the volume of flowing current.
