At DC, it interrupts 15 kA at 60 V (max 72 V operating), so it also handles DC distribution in control cabinets or solar combiner boxes. The UL 1077 rating of 5 kA confirms its acceptance as a supplementary protector in North American panels — not a branch-circuit primary, but a recognized component for internal equipment protection. This is a current-production part (lifecycle stage: current), so it is sourced through the standard Siemens distribution channel. ## Selectivity and coordination The 5SY7316-7 carries dual-standard breaking capacities: 15 kA under IEC 60898-1 (the household standard) and 25 kA under IEC 60947-2 (the industrial standard). The C-curve's magnetic trip threshold (5–10× In) also aids selectivity: a downstream B-curve breaker will trip first on a low-level fault, while this holds for the motor start. Rated for ambient temperatures from -40 °C to +75 °C, with humidity derating: max 95% RH at 55 °C, tapering to 35% at 75 °C. ## Panel integration Snaps onto 35 mm DIN rail via the quick-assembly system — no tools needed for mounting or removal. 3 MW units wide (54 mm), 70 mm installation depth behind the panel surface, 76 mm overall depth including the front. No neutral conductor switching — this is a 3-pole breaker for 3-phase loads only; the neutral must be handled separately if required.","metaTitle":"Siemens 5SY7316-7 SENTRON MCB, 3P C-Curve, 15kA IEC","metaDescription":"Siemens 5SY7316-7 SENTRON 3-pole MCB, C-curve, 15 kA (IEC 60898-1) / 25 kA (IEC 60947-2). 400 V AC, 60 V DC.
