It operates on 440 V AC at 50/60 Hz. The C-curve (tripping between 5 and 10 times rated current) suits it for moderate inrush loads like small motors, transformers, and banks of contactor coils — common in mechanical engineering and industrial applications. ## What the ratings mean for fit The 6 kA breaking capacity covers the majority of domestic and light industrial installations where the prospective short-circuit current stays under that threshold. Overvoltage category III and pollution degree 3 confirm it is rated for fixed installations inside a panel or enclosure. Temperature derating is built into the spec: at 40 °C the continuous current is 15.04 A, dropping to 14.02 A at 50 °C and 13.47 A at 55 °C. If the panel ambient runs hot, size the upstream protection accordingly — the 16 A nameplate rating is only valid at 35 °C. The 4-pole design (4P) switches all phases but does not switch the neutral — confirmed by the neutral conductor switching field set to No. That is typical for TN systems where the neutral is bonded at the source and does not require overcurrent protection. ## Panel integration and mounting Snaps onto DIN rail via the quick assembly system, occupying 4 modular width units (72 mm wide). Mounting position is any, which simplifies layout in crowded enclosures. Installation depth is 70 mm behind the panel face; overall depth is 76 mm. Combined terminals at both top and bottom accept the same conductor range, so line and load can be wired from either direction. The unit is sealable, halogen-free, and silicon-free — relevant for clean-room or food-production environments where outgassing must be controlled. IP20 protection with connected conductors means it is touch-safe once wired but not rated for washdown or outdoor exposure — keep it inside a locked enclosure rated to at least IP54.","metaTitle":"Siemens 5SY6416-7CC SENTRON MCB, 4P C16 6kA, 440V AC","metaDescription":"Siemens SENTRON 5SY6416-7CC miniature circuit breaker, 4-pole, C-curve, 16 A, 6 kA per EN 60898, 440 V AC.
