The Siemens SENTRON 5SV3312-6KK01 is a 2-pole residual current circuit breaker (RCCB), Type A, short-time delayed, rated 25 A and 30 mA residual sensitivity on a 230 V AC supply. The short-time delayed design means it tolerates brief surge currents (like those from connected electronics or lightning-induced transients) without nuisance tripping — useful on circuits feeding equipment with inrush or leakage that would trip a standard instantaneous RCCB.
Depth is 70 mm, matching the SENTRON miniature breaker family, so it sits flush in a pre-wired panel without extra clearance behind the rail. Mountable in any position; grid spacing of 60 mm means it aligns with standard busbar systems and comb-bus jumpers.
