IEC Manual Motor Starters Selection Guide

Section 6

Selection and Pricing Surion comprises a complete range of compact , reliable motor starters, rated from 0.1A to 63A, in 45mm and 55mm frame widths. It represents a motor protection system for switching and protecting three-phase induction motors to 50hp at 600 volts. Surion starters are available worldwide. They are specifically designed to deliver total connectivity with GE’s other IEC motor starters and controls, and they can be combined with our MC and CL contactors to form integrated solutions. A full complement of accessories create solutions for all types of applications. You can choose from frontal auxiliary and alarm contacts, lateral auxiliary contacts, alarm/auxiliary and short circuit trip indicators, shunt trip, undervoltage release (with or without early make auxiliary contacts), enclosures, group bus bars and more. You can also select assembled versions. Product Number Selection Instructions Selection of the starter depends on the actual motor full load current and service factor. For motors with service factor of 1.15 or greater, use motor full load current to select the appropriate current range. For motors with a service factor less than 1.15, multiply the normal full load current by .9 for the current setting. Single phase applications require all three overload legs to be energized for proper operation. Use separate conductor to connect terminal T2 to L3. Connect power to L1 and L2 and apply load between T1 and T3.
