Motor and Pump protection relay against over underload and phase loss

Electronic motor and water pump protection relay with three function in one relay:

  • (1) Overload 1 to 19,2 A. Detection by external current transformer.
  • (2) Underload 1 to 19,2 A. Detection by external current transformer.
  • (3) Phase failure/loss detection.
  • Modular plug-in format (2 modules).
  • Power supply: single voltage 230 or 400 Vac (depending on the model).
  • Protection of single-phase or three-phase motors.
  • Dry running detection application (without probes) in pumps whose consumption varies with underload.
  • Overload trip time: 7 s.
  • Underload trip time: 4 s (with 20 s starting inhibition).
  • Automatic re-start time after underload trip, selectablem and adjustable (up to 2 hours).
  • Manual re-start push-button (Reset).
  • 3 digits LED display for: measured current, trip current, remaining re-start time, overload alarm, underload alarm and setting values.
  • Setting values through thumbwheels with direct visualization on display.
  • Trip current is not influenced by environmental temperature.
  • Connection for EXTERNAL auxiliary control at 12 Vdc available (pressure switch, float switch, etc).
