The Siemens 5SV3614-6KK01 is a 2-pole residual current operated circuit breaker (RCCB) from the SENTRON series, type A, short-time delayed, rated 40 A with a 300 mA trip sensitivity on a 230/400 V AC supply. The short-time delayed design means it tolerates brief surge currents without nuisance tripping — useful on circuits with connected electronics or motor drives that produce a short inrush.
Depth is 70 mm; installation depth matches at 70 mm. The IP20 rating applies with the distribution board installed and conductors connected — standard for panel-internal use, not for wet-area standalone mounting.
Rated for ambient temperatures from -25 °C to 45 °C operating, with storage down to -40 °C. Silicon-free construction. Overvoltage category III. The product accepts installable supplementary devices.
