Time Mark 422

SUBMERS. PUMP CTRLR,(98052902)

This 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. This unit can be used with single phase pumps or, using the Model 276C current transducer, with 3-phase pumps. Matching CTs allow the Model 422 to be used with most pump motor sizes. Optional trip and restart delays are provided.
