Integrator's spec recap — 5SY7510-7
That neutral-switching feature matters for installations where an isolated neutral is required after the breaker opens, typical in single-phase sub-distribution or machine supply panels where you want both conductors positively disconnected. The breaker is rated for 230 V AC and carries a 15 kA breaking capacity per EN 60898, with a higher 30 kA rating per IEC 60947-2 for industrial panel duty where the prospective fault current is higher. For DC circuits it is rated 60 V at 15 kA per IEC 60947-2.
Certified to IEC / EN 60898-1 and IEC / EN 60947-2, plus UL 1077. Halogen-free and silicon-free construction. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. The sealable design allows lockout-tagout application. Energy limitation class 3.
