Its short-circuit current rating (SCCR) is 6 kA per the device's own rating, with an additional conditional rating of 0.5 kA according to EN 60898 and IEC 61008-1 — the 6 kA figure governs the upstream protective device coordination. Mounting position is unrestricted — horizontal, vertical, or flat. Depth is 70 mm, matching standard distribution board cutouts. The test button requires a minimum of 195 V to operate correctly. Rated operational voltage is 230 V AC, 50 Hz. Overvoltage category III (fixed installation). The device is instantaneous (no short-time delay), so it trips without intentional delay on a residual fault. Permissible let-through energy (I²t) is 58,000 A²·s, and the let-through current rating is 5,200 kA — these values define the thermal and magnetic stress the RCCB can withstand during a fault before the upstream breaker clears. Ambient operating range: -25 °C to +45 °C. Mechanical service life is 2,000 switching cycles typical. Silicon-free construction. Fits DIN 43880 size 1 enclosures.","metaTitle":"Siemens 5SV5312-0FC SENTRON RCCB, 25A, 30mA, 2-Pole, Type AC","metaDescription":"Siemens 5SV5312-0FC SENTRON RCCB, 25A rated, 30mA trip, 2-pole, Type AC, instantaneous. 6kA SCCR.

The 5SV5312-0FC is a pure RCCB (no overcurrent protection), while the 5SU9354-7KK16 is an RCBO (RCD + MCB in one unit).
