Blank/none X 4 The Extended Range Shunt Trip is specifically intended and required for UL ANSI Ground Fault applications. The pick up range is 55-110% of the ST coil voltage. When a motor is selected from the Spring Charging Motor (Digit 7) a Shunt Trip must be selected. SELECT ONE DEVICE ONLY.

Blank/None 1 X 1 An "X" (Blank/None) denotes a Manually Operated device (MO) Spring Charge Contact, GSCC1, included with all Motor Operators. NOTE: When a Spring Charging Motor is selected, a Closing Device must be selected from Closing Devices for Digit 8, and a Shunt Trip Device must be selected from Shunt Trip 1 Devices for Digit 9. Shunt Trip 1 with a coil voltage different from the Spring Charge Motor may be user selected. When a Motor & Spring Charge Contact is selected, the Ready To Close (RTC) (Digit 13) contact output options to the SD (Codes 1, 2, D, E, G, H, K, L) will be wired to the Spring Charge Contact location on the Secondary Disconnect Block. –

Blank/none X 5 The UVR Shunt Trip with Fixed Time Delay is specifically intended for applications where a delay period ('ride-through') is required due to potential voltage events. The design delays are 50msec when system voltage drops to 50% and 20 msec when system voltage drops below 50%. An optional External UVR Time Delay Module is available in a 1 - 3sec delay.

Blank/None X 2 The Closing Coil (CC) permits either local or remote release of the spring charged closing mechanism by electrical operation. 3 The Command Operated Closing Coil (CCC) includes an additional anti-pumping safety feature to ensure that the electrical closing signal must be released before further closure is attempted, a shut off is initiated if the closing signal is maintained. NOTE: Manual button through breaker cover is included as standard assembly. NOTE: When a Spring Charging Motor is selected (Digit 7), a Closing Device must be selected from Closing Devices for Digit 8, and a Shunt Trip Device must be selected from Shunt Trip 1 Devices for Digit 9.
