Per EN 60898 (the household / commercial standard) it's rated 10 kA at 230 V AC. Per IEC 60947-2 (the industrial standard for panel builders) it's rated 20 kA at 230 V AC, and 15 kA at 60 V DC. For UL 1077 / CSA C22.2 No. 235 applications it's rated 5 kA. ## Where it fits — panel integration IP20 with conductors connected.","metaTitle":"Siemens 5SY4508-7 SENTRON MCB, C-Curve, 1P+N, 10kA/20kA","metaDescription":"Siemens 5SY4508-7 SENTRON miniature circuit breaker, C characteristic, 1P+N, 10 kA (EN 60898) / 20 kA (IEC 60947-2).
