What is the short circuit current rating (SSCR) for the GV7R___ manual starters?
Tesys GV Manual Starter and Protectors
Maximum RMS symmetrical amps based on nominal system voltages as follows. For GV7RE40 through GV7RE220 at 240 or 480 vac = 25 kA, at 600 vac = 10 kA. For GV7RS40 through GV7RS220 at 240 or 480 vac = 65 kA, at 600 vac = 10 kA.
For Group Installation:
Maximum non-time delay fuse (NTD) 1200 amps.
Maximum circuit breaker 1200 amps. Suitable for use on a circuit with an available short circuit current level no greater than the short circuit current rating of the GV7R__ manual controller , or circuit breaker, whichever is les.
