Rated 30 kA at 230 V AC per IEC 60947-2, it safely interrupts fault currents up to that level in industrial panels; the UL 1077 supplementary-protector rating of 5 kA covers North American branch-circuit applications. The 2-pole 1P+N design switches both phase and neutral, with neutral conductor switching built in, so it suits single-phase sub-distribution where you need to isolate the neutral. The quick-assembly system and combined top/bottom terminals speed up panel wiring.
The 5SY8532-8 carries IEC / EN 60947-2 and UL 1077 approvals, covering both international and North American installations. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) and a mechanical life of 10 000 operating cycles confirm it for frequent switching in mechanical engineering and industry applications.
