It's built for residential and infrastructure distribution boards, protecting branch circuits against overload and short-circuit. It switches the neutral conductor, so it's a drop-in for single-phase final subcircuits where both line and neutral need isolation. The C-curve means the magnetic trip fires at 5–10× In — so 80–160 A for this 16 A breaker. That's the standard choice for general-purpose socket circuits and small inductive loads where you want nuisance-tripping immunity from inrush but still need fast short-circuit clearance. If your panel's prospective short-circuit current exceeds 6 kA, you'd step up to the 10 kA class (like the SENTRON 5SL series). Temperature derating is already on the nameplate: at 40 °C ambient the breaker carries 14.78 A continuous, and at 45 °C it's 14.08 A. Above that, size the downstream load to the derated figure or move to a higher-rated frame. Sealable for lockout/tagout. Halogen-free and silicon-free — relevant if the panel sits in a cleanroom or a zone with strict outgassing limits.","metaTitle":"Siemens 5SJ6516-7FC SENTRON MCB, 2-pole C 16A, 6kA","metaDescription":"Siemens SENTRON 5SJ6516-7FC miniature circuit breaker, 2-pole, C-curve, 16A, 6kA breaking capacity per EN 60898.
