The 15 kA figure also holds at 60 V DC per IEC 60947-2, so it works in DC control circuits up to 72 V DC maximum. Halogen-free and silicon-free construction, sealable for panel lockout. ## Breaking capacity — what the dual rating means for your BOM The 5SY6216-6 carries two breaking capacity ratings because it is certified under both the wiring-rule standard (EN 60898-1: 6 kA) and the industrial standard (IEC 60947-2: 15 kA). The 6 kA figure governs residential or light commercial panels; the 15 kA figure applies when the breaker is specified per IEC 60947-2 in an industrial switchboard. The UL 1077 supplementary-protector rating is 5 kA at AC. For a panel builder working to IEC 61439, the 15 kA rating is the one that drives selectivity and SCCR coordination upstream. Two modular-width units (36 mm) on standard DIN rail. Combined terminal top and bottom accepts supply from either end. Neutral conductor is not switched (2-pole, both poles are phase). Sealable for lockout/tagout.","metaTitle":"Siemens 5SY6216-6 SENTRON MCB, 2-Pole B-Curve, 6 kA","metaDescription":"Siemens 5SY6216-6 SENTRON 2-pole miniature circuit breaker, B characteristic, 6 kA per EN 60898-1, 15 kA per IEC 60947-2. 400 V AC, 36 mm wide.
