For a 16 A breaker, magnetic trip is typically around 8–14× In, so it's a fit for transformer inrush or groups of small motor starters where a C curve would nuisance-trip but a D curve might delay too long on a hard fault. ## Thermal derating — don't ignore it Rated 16 A at 30 °C, but the continuous current drops to 15.2 A at 40 °C, 14.8 A at 45 °C, 14.4 A at 50 °C, and 14 A at 55 °C. Occupies 4.5 modular width units — that's 81 mm of rail space. IP40 with conductors connected, pollution degree 3, overvoltage category IV. Integrated locking slide accepts a padlock, wire seal, or cable tie for lockout/tagout.","metaTitle":"Siemens 5SP3316-3 SENTRON MCB, 16A 3P E-Curve 25kA","metaDescription":"Siemens 5SP3316-3 SENTRON miniature circuit breaker, 16A rated, 3-pole, E tripping characteristic, 25 kA breaking capacity per EN 60898.
