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.
Power Components:
• 6 SCRs in inverse parallel pairs for full phase angle soft start control
• 1600V PIV rating on all units
