Applies to three-pole units for public and industrial distribution systems that are functional assemblies of switches including switch-disconnectors and current-limiting fuses designed so as to be capable of breaking, at the rated recovery voltage, any current up to and including the rated short-circuit breaking current, and making, at the rated voltage, circuits to which the rated short-circuit breaking current applies. Does not apply to fuse-circuit-breakers, fuse-contactors, combinations for motor-circuits or to combinations incorporating single capacitor bank switches.
