The Eaton FAZ-C3/3-NA-AS is a C3 ampère, 3-pole set of UL Class CC fuses. This specific variant is a current-limiting, fast-acting fuse that is non-indicating and features a special "AS" (Anti-Surge) time-delay characteristic. Its primary function is to provide short-circuit protection and overload protection for circuits that experience moderate temporary inrush currents, such as those found in transformers, solenoids, or certain types of lighting. The "Anti-Surge" feature allows it to withstand these brief current surges without nuisance blowing, while still providing fast-acting protection against dangerous short-circuits.
