This is the core spec that determines fit for a final-sub circuit — the 63 A frame handles the load side, the 30 mA sensitivity catches both sinusoidal and pulsating DC fault currents (Type A), which covers most modern electronics and variable-speed drives downstream. Mounts on DIN rail (REG), occupies 2 width units, installs in any position, and needs 55 mm of enclosure depth. The IP20 rating applies once the distribution board is closed with conductors connected. ## Thermal derating and conductor sizing Above that, the curve steps down: 60.48 A at 50 °C, 57.96 A at 55 °C, 55.44 A at 60 °C, 52.92 A at 65 °C, and 50.4 A at 70 °C. Terminals accept 1.5 mm² minimum to 25 mm² maximum conductor. That 25 mm² top end matches the 63 A rating comfortably. ## Integration notes Supply can land top or bottom — no mandatory orientation. The instantaneous design (no short-time delay) means it trips on the first half-cycle of a residual fault, which is the standard for personnel protection (30 mA). The 1 kA surge-current withstand rating covers inrush from downstream capacitive loads or surge arrestors without nuisance tripping. Mechanical endurance is 10,000 switching cycles typical. Silicon-free construction matters for automotive or electronics manufacturing environments where silicone outgassing can contaminate sensitive surfaces or bonding processes. Finger-and-back-of-hand shock protection means the terminals are shrouded against accidental contact during commissioning.","metaTitle":"Siemens 5SM1316-6 SENTRON RCCB, 63A 30mA Type A, 2-Pole","metaDescription":"Siemens 5SM1316-6 SENTRON 2-pole RCCB, 63A rated, 30mA type A, 230V AC.
