The F2 tripping characteristic is a fast-acting curve that sits between the standard B and C curves; it trips within 0.1–5 seconds at 4–7 times rated current, making it suited for protecting semiconductor loads, control transformers, and sensitive electronics where a standard MCB would be too slow. The auxiliary switch provides a separate signal contact for remote status monitoring or PLC input — useful in a panel where you need to know the breaker has opened without running a separate sensor. Rated to IEC / DIN EN 60934 and UL1077, this is a supplementary protector, not a branch-circuit rated device. In a UL panel, it goes downstream of a branch-circuit overcurrent device. In a warm cabinet, the continuous current drops: 15.47 A at 35 °C, 14.67 A at 40 °C, 14.25 A at 45 °C, 13.82 A at 50 °C, 13.38 A at 55 °C, and 12.93 A at 60 °C (–). If your panel ambient runs 50 °C, plan for a 13.8 A continuous load maximum — not 16 A. The device also carries a humidity derating: 30 °C at 85% rF, 60 °C at 20% rF. ## Integration notes Fastens on standard DIN rail. The auxiliary switch (1P+AS) is wired separately from the main load circuit; it changes state when the breaker trips or is manually switched off. No neutral conductor switching, no combined top or bottom terminals — line and load are separate.","metaTitle":"Siemens 5SY1716-4 SENTRON Device Protection Switch, 16 A, F2","metaDescription":"Siemens 5SY1716-4 SENTRON device protection switch, 1-pole with auxiliary switch (1P+AS), 16 A AC, F2 characteristic, rated to IEC/DIN EN 60934 and UL1077.
