It switches the neutral conductor along with the phase, which matters for installations where full isolation is required on both poles. For DC circuits, it's rated 15 kA up to 72 V, so it also handles battery-backed or rectifier-fed loads. The sealable feature lets you lock the handle position for lockout/tagout on the line side. Rated for ambient temperatures from -40 °C to 75 °C, with humidity influence capped at 95% up to 55 °C, derating to 35% at 75 °C. Halogen-free and silicon-free construction, which is often a spec for clean-room or semiconductor-adjacent panels. The lifecycle status is current production (active). ## Approvals and standards Rated under IEC 60947-2 (70 kA at 230 V AC, 15 kA at 72 V DC) and UL 1077 / CSA C22.2 No. 235 (5 kA at 230 V AC). The part carries the IEC 81346-2 designation F for protective devices. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.","metaTitle":"Siemens SENTRON 5SY8515-7 MCB, 1P+N, C-curve, 1.6 A, 70 kA","metaDescription":"Siemens SENTRON 5SY8515-7 miniature circuit breaker, 1P+N, C-curve, 1.6 A, 70 kA IEC 60947-2, 5 kA UL 1077. 36 mm wide, IP20, halogen-free.
