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

EAN: 8595188182713 | Code: 8271

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.
