421 Motor Load Monitor from Time Mark

421, Motor Load Monitor, Time MarkThe Model 421 Motor Load Monitor detects an overload or under-load condition on all types of running motors; conveyor motors, elevator motors, mixer motors, submersible pumps, suction pumps, etc. The monitor detects the actual power used (voltage x current x power factor) and is more sensitive than simple current monitors.

The Model 421 Motor Load Monitor can be used with single-phase motors, or using the Model 276C Current Transducer, with three-phase motors. Matching CTs allow the Model 421 Motor Load Monitor to be used with virtually any size of motor. Trip and restart delays are provided; one or both can be turned on or off.

  • Monitors true motor power (volts x current x power factor)

  • Detects motor overload and underload

  • Operates on 120 or 240 VAC, single-phase or three-phase

  • Trip and restart delays can be turned on or off
