It carries a 10 kA short-circuit current rating (SCCR). The 80 A rating holds at 40 °C and 45 °C; above that, derate linearly to 64 A at 70 °C — a curve worth checking if the RCCB sits in a warm enclosure or next to heat-generating contactors. Wire terminals accept 1 to 16 mm² solid or stranded, torqued to 2.5–3 N·m. Supply can land top or bottom — no mandatory orientation. It remains a standard catalog item in the SENTRON 5SM1 family.","metaTitle":"Siemens 5SM1617-0 SENTRON RCCB, 2-pole, 80A, 300mA, Type AC","metaDescription":"Siemens 5SM1617-0 SENTRON RCCB, 2-pole, 80A rated at 40°C, 300mA trip, Type AC, 10kA SCCR.
