AS-30 Switch Operators for Alduti-Rupter Switches. Superior to ordinary overcurrent relays, they can distinguish between fault current and transformer magnetizing inrush current. Type ZSD Overcurrent Relays, applied on individual load feeders, provides three-phase isolation after a downstream fault has been detected and cleared. Micro-AT ® Source-Transfer Control s minimize interruptions resulting from the loss of one source, and transfer is achieved in as little as 20 to 25 cycles. Type MS operators are available in a choice of manual or automatic Trip Closed operation. Type MS Switch Operators provide high-speed automatic Trip Open operation of Mini-Rupter Switches, and the interrupting time is 4 cycles. Fault Fiter ® Electronic Power Fuses-rated through 600 amperes max continuous (They have exceptional TCC versatility and higher continuous current ratings than previously available in fuses.). The TCC curves are precise and permanently accurate.) Fuses are offered in a wide variety of time-current characteristic (TCC) curves for optimal coordination and maximum protection. Type SM-40 Power Fuse-rated 400 amperes max continuous (Other Type SM power fuses are available in ratings from 200 through 720 amperes max continuous. Alduti-Rupter ® Switch-rated through 1200 amperes continuous and interrupting are also available. Mini-Rupter ® Switch-rated through 600 amperes continuous and interrupting. For other applications, short circuit rating is 25 000 amperes RMS, Sym. ♦ This rating is for transformer switching and protection only. 
▲ Rating is 12 500 amperes on solidly grounded circuit with single-conductor concentric neutral cable or bus connection to transformer. ■ The Max rating is reduced to 27 kV if using fuse types SM-4Z, SM-20, or SM-5S. Rating is 27 000 amperes for a 7.2-kV refill. For 2000-A and 3000-A main-bus ratings, please contact S&C. The rating for the entire assembly is the same as the lowest-rated bay. ① The ratings shown here are for individual bays.
