The 40 A rating is the continuous load current at 40 °C ambient; above that, the thermal derating curve applies (38.4 A at 50 °C, 36.8 A at 55 °C, stepping down to 32 A at 70 °C). The instantaneous design (no intentional delay) trips within milliseconds on a ground fault — no coordination with short-time-delay RCCBs downstream. The IP20 rating applies once the distribution board is installed with conductors connected; the front is finger- and back-of-hand safe per the protection class. Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded; strip length 8 mm.","metaTitle":"Siemens 5SM1314-6 SENTRON RCCB, 2-pole, 40 A, 30 mA, Type A","metaDescription":"Siemens 5SM1314-6 SENTRON RCCB, 2-pole, 40 A, 30 mA, Type A, 230 V AC, 10 kA SCCR, DIN rail.
