Rated at 230 V AC (50/60 Hz) and 60 V DC (max 72 V), it covers standard industrial supply voltages. ## Standards and approvals — what they certify Listed to IEC / EN 60947-2 (the low-voltage switchgear standard for industrial applications) and UL 1077 (supplementary protectors for North America). The UL 1077 path gives a 5 kA interrupting rating at 250 V AC single-phase — enough for most panelboard supplementary protection, but lower than the IEC 30 kA figure. The DC rating per IEC 60947-2 is 15 kA at 60 V. Sealable terminals (top and bottom combined) allow tamper-proofing after commissioning. ## Environmental range and derating Rated for ambient temperatures from -40 °C to +75 °C, with humidity derating: max 95% RH up to 55 °C, tapering to 35% at 75 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — sufficient for most industrial machinery and conveyor lines.","metaTitle":"Siemens 5SY8516-7 SENTRON MCB, 2-Pole C-Curve, 30kA IEC","metaDescription":"Siemens 5SY8516-7 SENTRON miniature circuit breaker, 2-pole 1P+N, C-curve, 30kA breaking capacity per IEC 60947-2.
