At 54 mm wide (2 modular width units) and 76 mm deep, it fits standard DIN-rail enclosures without needing extra gutter space behind the rail — the 70 mm installation depth means the breaker body clears most 80 mm deep enclosures. Dual-standard certification (IEC/EN 60898-1 and IEC/EN 60947-2 plus UL 1077 / CSA C22.2 No.235) means this breaker carries the documentation needed for both European and North American panel approvals — the UL 1077 listing at 5 kA is the limiting figure for US installations, so factor that into the SCCR calculation if the panel ships stateside. ## Integration Notes Sealable design lets the panel builder lock the breaker in the ON or OFF position for lockout/tagout compliance without an external hasp. ## Ratings & Environment The humidity derating table caps relative humidity at 95 % up to 55 °C, then steps down — so in a sealed panel near a dryer or kiln, confirm the internal microclimate stays within the curve. DC rating of 15 kA at 60 V (max 72 V operating) per IEC 60947-2 makes this usable for DC distribution in solar combiner boxes or battery circuits, though the B-curve may trip faster on DC than a C-curve would — verify coordination with the downstream DC loads.","metaTitle":"Siemens 5SY4315-6 SENTRON MCB, 3P, B-Curve, 10 kA","metaDescription":"Siemens 5SY4315-6 SENTRON 3P miniature circuit breaker, B-curve, 10 kA per IEC 60898-1, 35 kA per IEC 60947-2.
