Five-pin (3P+N+E) trailing socket for 400 V three-phase 63 A leads, the size used for site distribution and larger three-phase plant. Takes 6 to 16 mm² conductors, so it terminates the heavy flexible cable a 63 A run needs. IP44 splashproof, for outdoor and site use where water is splashed rather than jetted. Runs at 50 or 60 Hz, so it suits generator and marine 60 Hz supplies as well as mains. GARO S463-6S.
