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. The 10 kA short-circuit current rating (SCCR) per IEC 61008-1 (0.5 kA) ensures it can safely interrupt a fault up to that level without upstream damage.
Mounting and integration
Snaps onto a DIN rail (REG) and occupies 2 modular width units (36 mm wide) at a 60 mm grid spacing. Mounting position is any orientation, so it fits tight enclosures. 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.
Environmental and compliance
Rated for ambient temperatures from -25 °C to 45 °C operating, with storage down to -40 °C. Silicon-free construction. Overvoltage category III. Power supply cord can enter from top or bottom. The product accepts installable supplementary devices. Mechanical service life is 10 000 operating cycles typical.
