With Full Rated Wired Emergency Bypass
Features:• Separate start and run overload protection:• Two programmable overload trip curves allow for the thermal• capacity required to start the load, while providing more closely• matched overload protection during the run time.• Integral bypass contactors are standard on all sizes• and can soft start most any load.• Real-time thermal modeling a dynamic thermal register• continuously calculates motor operating temperature• even when your motor isn't running.• PTC thermistor input for use on motors with embedded• PTC temperature sensors.• Current imbalance trip and biasing of the thermal register.• Electronic shear pin trip (overcurrent) with trip delay.• Phase loss protection bases on current and voltage.• Equipment ground fault trip and monitoring.• Load loss trip (under current) with trip delay.• Pre-start shorted load protection checks for motor lead • or winding damage.
