MotorSaver™ Three-Phase Voltage Monitor 455 Series

MotorSaver™ Three-Phase Voltage Monitor

 

The Model 455 three-phase voltage monitor combines load and line-side monitoring to alert the user of contact failure or impending contact failure. The line-side monitoring will protect the motor from damaging line-side conditions prior to the motor starting. With the Model 455, your motor is fully protected at all times. The motor will not start if a power problem is present. The monitor is equipped with an infrared LED to communicate with the handheld diagnostic tool, the Informer-MS, to display MotorSaver® data to assist in monitoring and troubleshooting the system. Motor run hours, displayed by the Informer-MS can now be reset on the Model 455.
