Rated operating voltage is 400 V AC (multi-phase or single-phase) and 880 V DC, with a maximum DC voltage of 1 000 V. That DC rating is unusual for a 4-module-width MCB — it covers battery banks, UPS systems, and solar combiner boxes where the string voltage runs high. It mounts in any position and uses the quick-assembly system — clips onto the rail without tools. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, which is enough for most industrial panels unless you're mounting directly on a high-vibration pump skid. The 5SY5463-6 is certified to IEC/EN 60898-2 and UL1077, which means it's accepted in both IEC and North American panels (UL 1077 is the supplementary protector standard). It's halogen-free and silicon-free, so it won't outgas corrosive compounds in a sealed enclosure.","metaTitle":"Siemens 5SY5463-6 SENTRON MCB, 4P B-Curve, 10 kA, 400 V AC","metaDescription":"Siemens 5SY5463-6 SENTRON miniature circuit breaker, 4-pole, B-curve, 10 kA breaking capacity per IEC/EN 60898-2 and UL1077.
