That D characteristic means it handles high inrush currents — motor starts, transformer energization, welding equipment — without nuisance tripping on the magnetic release. The 10 kA rating at 400 V gives you selectivity headroom downstream of a larger feeder breaker in a 400 V panel. ## Ratings & Compliance Breaking capacity: 10 kA per EN 60898, 5 kA per UL 1077 and CSA C22.2 No. 235. That UL/CSA supplementary protector rating matters if the panel ships to North America — the 5 kA SCCR at 400 V is enough for most branch circuits behind a current-limiting feeder. Halogen-free and silicon-free construction meets clean-room and high-reliability specs.","metaTitle":"Siemens 5SY4310-8CC SENTRON MCB, 3P D 10 A, 10 kA","metaDescription":"Siemens 5SY4310-8CC SENTRON miniature circuit breaker, 3-pole, D-curve, 10 A, 10 kA per EN 60898.

The difference is the tripping curve: 5SY4310-8CC is D-curve (10–20× In magnetic trip), while 5SY6332-7CC is a different characteristic — verify the load's inrush profile before swapping. No rewiring needed for the same footprint."},{"question":"What compliance documentation does this brand provide for 5SY4310-8CC?","answer":"The SENTRON series carries EN 60898 (IEC) and UL 1077 / CSA C22.2 No. 235 certifications.
