The AC-type detection covers sinusoidal residual currents only. The 5SM3614-0 carries its full 40 A rating up to 45 °C ambient; above that it derates linearly to 32 A at 70 °C. In a crowded DIN-rail enclosure, consider the internal temperature rise from adjacent breakers and contactors — the derating curve is real and starts at 45 °C. The IP20 rating applies with the distribution board installed and conductors connected — this is a protected-enclosure device, not for open-panel washdown zones. Mounting position is unrestricted, and supply may enter from top or bottom — useful when reworking an existing panel layout without flipping the busbar arrangement.","metaTitle":"Siemens 5SM3614-0 SENTRON RCCB, 40A 2P 300mA AC, IP20","metaDescription":"Siemens 5SM3614-0 SENTRON RCCB, 40 A rated, 230 V AC, 2-pole, 300 mA trip, 10 kA SCCR.
