Undercurrent monitoring relay in 1P - AC by external CT - PRI-35

DESCRIPTION

• 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.
