The 30 mA sensitivity covers personnel protection (≤ 30 mA is the IEC threshold for direct-contact shock protection). ## Thermal derating and conductor sizing Above that the current must be derated: 24 A at 50 °C, stepping down to 20 A at 70 °C. The terminal range accepts 1.5 mm² minimum to 25 mm² maximum — the 25 mm² upper limit covers most 25 A feeder conductors in copper, so no lug adapter is needed for standard panel wiring. Mounting position is unrestricted — top or bottom feed is acceptable. The IP20 rating applies once the distribution board is closed and conductors are connected; the enclosure itself provides the environmental seal. Finger and back-of-hand touch protection is built in, meeting the shock-protection requirements for live-terminal access inside a locked panel.","metaTitle":"Siemens 5SM1352-6 SENTRON RCCB, 4P, 25A, 30mA, Type A, 500V","metaDescription":"Siemens 5SM1352-6 SENTRON 4-pole RCCB, 25A rated, 30mA trip, Type A, 500V AC, 10kA SCCR.
