The B/W/ floatless induction type liquid level control system provides automatic low level cutoff protection for Submersible Well Pumps. Can be used as a pump-down or a pump-up water level control depending on contact arrangement. Note: Control is factory set for pump-down operation


    Specifications

  • Pump-down: Pump starts when water level in the cistern, tank or well reaches upper electrode and stops when water level drops below the lower electrode.
  • Contact Arrangement for Pump-down: 2 Normally Closed (N.O)0 Normally Open (N.O.)
  • Pump-Up: Pump Stops when water level reaches the upper electrode and starts when water drops below the lower electrode.
  • Contact Arrangement for Pump-up: 1 Normally Open (N.O.)1 Normally closed (N.C.)
  • Enclosure: Nema 1 general purpose
  • Contact rating: 25 amps at 120. 240 or 480 Volts; 1 HP Single Phase at 120 or 240 Volts
  • Ground: A ground is required from the indicated relay terminal to the liquid in order to complete the secondary circuit of the relay. Connection should be made directly to the uninsulated metal tank, or to metal pipe connected to the tank below the normal liquid level control. in wells, concrete, or insulated metal tanks, an extra common electrode extending slightly below the longest operating electrode is used.
  • Electrodes: Three required (upper, lower and ground)
  • Carton dimensions: 4-1/4" H X 6" W X 4-1/4" L
  • Weight: 6 lbs
