It breaks fault currents up to 10 kA per EN 60898 and 35 kA per IEC 60947-2, with a DC rating of 15 kA per IEC 60947-2 and 5 kA per UL 1077 / CSA C22.2 No. 235. Rated for 400 V AC phase-to-phase and 72 V DC maximum, this breaker suits industrial control panels, machinery disconnects, and distribution sub-feeds. ## Breaking Capacity & Selectivity The dual breaking-capacity rating is the key differentiator here: 10 kA under EN 60898 (the domestic / light commercial standard) and 35 kA under IEC 60947-2 (the industrial standard). That 35 kA IEC rating gives headroom for high-fault installations — substation secondaries, large motor control centers, or panelboards with upstream transformers above 500 kVA. The UL 1077 supplementary-protector rating of 5 kA means it's accepted in North American panels as branch-circuit protection for dedicated loads, not as a service disconnect. ## Installation & Wiring Mounts via the quick-assembly system (DIN rail 35 mm) in any position — horizontal, vertical, or upside-down — with an installation depth of 70 mm and overall dimensions 72 mm wide × 90 mm high × 76 mm deep. The 4-pole body occupies 4 width units (72 mm) on the rail. Touch protection meets IP20 with connected conductors. Humidity tolerance: max 95% RH at 55 °C, derating to 55% at 70 °C and 35% at 75 °C. Halogen-free and silicon-free construction suits clean-room, food-processing, or marine environments where outgassing must be minimized. Approvals include EN 60898, IEC 60947-2, UL 1077, and CSA C22.2 No. 235, covering installations across Europe, North America, and most global markets. The product designation (F per DIN EN 61346-2 / 81346-2) aligns with standard protection-device labeling in panel schematics.","metaTitle":"Siemens 5SY4615-8 SENTRON MCB, 4P D-1.6A, 10kA EN","metaDescription":"Siemens 5SY4615-8 SENTRON miniature circuit breaker, 4-pole D-curve 1.6 A, 10 kA (EN 60898) / 35 kA (IEC 60947-2).
