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
Designed to protect a motor of a pump (submersible pump) against dry running.
Monitor a current of a motor by means of current transformer (CT) X/5A.
Current level (ISET) and TRIP delay (t) are adjustable by potentiometers
Indication of operating states by the red LED on the front panel.
The power supply is not galvanically separated from the monitored current terminals, terminals A2, B2 are internally connected
Wiring between B1, S1 and B2, S2 must be insulated and not connected to any external voltage or ground.
External current transformer X/5A must be used.
