It is a 2-pole unit (2P) occupying 2 modular width units (36 mm wide), designed for snap-on DIN-rail mounting in distribution boards or subpanels where branch-circuit overcurrent and short-circuit protection is required. The 6 kA breaking capacity per EN 60898 means this MCB can safely interrupt fault currents up to 6,000 A at 415 V AC without welding its contacts or cascading failure upstream. In a typical commercial retail-line installation, this covers most branch-circuit fault levels; if the prospective short-circuit current at the panel exceeds 6 kA, you need a higher-rated unit (e.g., the 10 kA 5SL series). Rated 415 V AC multi-phase operation (440 V max), 2-pole switches both line conductors. Suitable for indoor panel environments only. ## Panel integration and mechanical fit Depth is 76 mm (70 mm installation depth behind the panel surface), height 90 mm. The 36 mm width (2 MW) means it occupies two adjacent 18 mm slots in a distribution board — check your busbar comb arrangement if replacing a 1-pole unit. Halogen-free and silicon-free construction means the plastic housing does not emit corrosive or conductive gases when burned — a requirement for railway, metro, and data-center environments where fire-gas toxicity matters.","metaTitle":"Siemens 5SJ6216-7RC SENTRON MCB, 2P 16A C-Curve 6kA","metaDescription":"Siemens SENTRON 5SJ6216-7RC miniature circuit breaker, 2-pole, 16A, C characteristic, 6 kA per EN 60898, 415 V AC.
