520CP-460 MotorSaver



Model 520CP-460 is a fully programmable, microcontroller-based, current sensing device designed to monitor 3-phase pumps (400-500VAC) or systems with ramp up times of 4 seconds or less.

  • 520CP Protects motors from:
    • Overload or jammed impeller
    • Underload or dry well
    • Current unbalance
    • Current single phase
    • Reverse phase
    • Rapid cycling
  • 3-digit LED diagnostic display
  • Last fault diagnostics
  • Automatic or manual reset
  • Remote reset capability
  • UL listed
  • CSA approved
  • 5-year warranty
  • Made in USA

Three external current transformers must be utilized in conjunction with the Model 520CP. The following 9 set points can be set and viewed from the 3-digit alphanumeric LED: overcurrent trip point, undercurrent trip point, current unbalance trip point, trip delay, rapid cycle timer (RD1), overload restart delay (RD2), underload restart delay (RD3), number of restarts after an overload, and number of restarts after an underload fault. Last fault diagnostics is also viewable. When a harmful condition is detected, the 520CP’s output relay is deactivated after the specified trip delay. The output relay reactivates after the appropriate RD2 or RD3 timer has expired. If the pump is started on a single-phase or a reverse-phase condition, the Model 520CP deactivates its output relay in 0.5 seconds.
