The E-curve (typically between B and C for inrush handling) makes it suited for resistive and general loads in residential and infrastructure applications, not motor starting. The 690 V insulation voltage (Ui) and overvoltage category IV rating confirm this breaker is designed for the main incoming supply side of an installation — not just downstream branch circuits. Temperature derating is built in: at 30 °C ambient it carries the full 16 A; at 40 °C it derates to 15.2 A, at 50 °C to 14.4 A, and at 55 °C to 14 A. If your panel runs hot (common in crowded enclosures), use the 40 °C or 50 °C figure for sizing, not the 30 °C label rating. The infeed can be at the box terminal (line side) or either end — the breaker is rated for any power supply position, so no orientation restrictions during wiring. The integrated locking slide accepts a padlock, wire seal, or cable tie for lockout/tagout compliance. The SENTRON series is Siemens' standard MCB platform, widely used across European and Middle Eastern installations. Compliance documentation (CE, RoHS, REACH) is standard with the brand; the EN 60898 and IEC 60947-2 certifications cover the breaking capacity and operational performance.","metaTitle":"Siemens SENTRON 5SP3416-3 MCB, 4P, 16A, 25kA, E-Curve","metaDescription":"Siemens SENTRON 5SP3416-3 miniature circuit breaker, 4-pole, 16 A rated, 25 kA breaking capacity at 400 V AC, E tripping characteristic, 50 Hz, IP40, standard rail mount.
