The 2-pole design switches both phase conductors, which is what you need for a single-phase 230 V load or a two-phase leg of a three-phase distribution board. The 6 kA breaking capacity at 400 V is adequate for most residential and light commercial service-entrance panels where the prospective fault current stays under that level; if your transformer or utility feed can deliver more, you'll need to step up to a 10 kA or higher-rated MCB in the same SENTRON family. The 36 mm width (2 modular units) and 76 mm depth let it snap onto a standard DIN rail in any mounting position. The 5SL6216-8CC occupies 2 modular width units (36 mm) on a 35 mm DIN rail, with a 70 mm installation depth behind the panel surface. The sealable design lets you lock the toggle position with a lead seal or a small padlock — useful for circuits that must stay locked off during maintenance. Power loss per pole at rated current is 2.8 W in hot operating state, so in a densely packed enclosure with multiple MCBs side by side, account for the cumulative heat; the 75 °C maximum ambient is the upper limit for the enclosure interior, not just the room temperature. ## Compliance and approvals It carries the EN 60898 rating for 6 kA breaking capacity at 400 V AC, 50/60 Hz. Vibration resistance tested to 50 m/s² at 25 to 150 Hz per IEC 60068-2-6, so it holds up on machinery that shakes.","metaTitle":"Siemens 5SL6216-8CC SENTRON MCB, 2-pole D 16A, 400V 6kA","metaDescription":"Siemens SENTRON 5SL6216-8CC miniature circuit breaker, 2-pole, D-curve, 16A, 400V AC, 6kA breaking capacity per EN 60898.

The depth and height are identical at 76 mm and 90 mm, so the DIN-rail mounting and enclosure cutout height are the same, but you need two modular width units of space instead of one, and the wiring differs because the 2-pole breaker switches both phase conductors."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6216-8CC","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SL6216-8CC when reusing this data.
