WWEHD Heavy Duty Reduced Voltage - Soft Starters

Features

• Three wire in, three wire out installation
• Service Entrance Rated
• Integral bypass contactors are standard on all sizes
• Over current capacity : 500% for 60 seconds
• Real-time thermal modeling and dynamic thermal register continuously caluculates motor operating temperature even when your motor is not running
• Phase loss protection based on current and voltage
• Separate across the line overload protection
• Load loss trip (under current) with trip delay
• Pre-start checks for shorted load prior to each start
• 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
• 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
• Equipment ground fault trip and monitoring
• Load loss trip (under current) with trip delay
