Siemens SENTRON 5SL6316-6CC is a 3-pole miniature circuit breaker rated 16 A with a B tripping characteristic and 6 kA breaking capacity per EN 60898. It operates on 400 V AC (multi-phase), with a maximum of 440 V AC. This 5SL6CC variant is sealable, halogen-free, and silicon-free — useful for installations that require tamper evidence or where outgassing must be minimized. The enclosure is IP20 with conductors connected, overvoltage category III, and energy limiting class 3. It accepts solid or stranded copper from 0.75 to 25 mm² at the screw terminals, tightened to 2.5–3 N·m. The 5SL6316-6CC occupies 3 width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. Mounting position is unrestricted. It withstands vibration at 50 m/s² from 25 to 150 Hz per IEC 60068-2-6.
The 54 mm width (3 modules) matches the standard modular grid for enclosure layout planning.
