Time Mark Corp. Model 422 Submersible Pump Controller


The Time Mark Model Model 422 Submersible Pump Controller detects an overload or underload condition on all types of running pump motors: suction pumps, submersible pumps, etc. This monitor detects the actual power used (voltage x current x power factor) and is more sensitive than simple current monitors. The 422 can be used with single phase pumps or, using the Model 276C current transducer, with 3-phase pumps. Matching CT’s allow the Model 422 to be used with most pump motor sizes.


  • Monitors True Motor Power (volts x current x power factor)
  • Detects motor overload and underload
  • Operates on 120 or 240 VAC, single-phase or 3-phase
