Its 6 kA breaking capacity, certified per both EN 60898 and IEC 60947-2, handles standard residential and infrastructure branch-circuit faults without cascading upstream. The B-curve trips between 3 and 5 times rated current, making it a fit for resistive and general-purpose loads where inrush is moderate — think lighting, socket outlets, or control transformers. Rated for 50/60 Hz networks, it occupies 3 modular width units (54 mm) on a DIN rail. ## Thermal derating and real-world current The 10 A rating holds at 30 °C ambient. At 40 °C it derates to 9.52 A, at 45 °C to 9.2 A, and at 55 °C to 8.74 A. If the panel runs warm — common in a crowded enclosure — the continuous load should be sized against the derated figure, not the 30 °C number. The 1.6 W power loss per pole at rated current in hot operating state adds up; for a 3-pole breaker that's 4.8 W dissipated inside the enclosure, so ventilation or spacing matters when grouping several MCBs. ## Panel integration and environmental limits Mounts in any position on a DIN rail; the 54 mm width (3 MW) and 76 mm depth fit standard distribution boards. Installation depth is 70 mm. Rated IP20 with connected conductors — fine for enclosed panels, not for washdown zones. The operating temperature range spans -40 °C to 75 °C, covering most indoor and sheltered outdoor cabinets. Pollution degree 2 and overvoltage category III are typical for fixed-installation branch circuits. Sealable, halogen-free, and silicon-free construction matters for environments sensitive to outgassing (clean rooms, medical, or certain industrial zones). ## Supplementary devices and mechanical endurance The design accepts installable supplementary devices (auxiliary switches, shunt trips, alarm contacts) — useful for remote status or emergency-off integration. Mechanical service life is rated at 10,000 operating cycles typical, which covers routine switching for a panel's service life. Energy limitation class 3 means it limits let-through energy well, reducing stress on downstream equipment during a fault.","metaTitle":"Siemens 5SL6310-6 SENTRON MCB, 3P B-10A 6kA 400V","metaDescription":"Siemens 5SL6310-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 10 A, 6 kA breaking capacity per IEC 60897.
