The Siemens 5SY4116-5 is a single-pole miniature circuit breaker suitable for mechanical engineering and industrial applications. It operates with a rated supply voltage of 400V AC and features a tripping characteristic class of A.
This circuit breaker has a rated operational current of 16A at 35°C and a switching capacity of 10kA according to EN 60898. It is designed with a mechanical service life of typically 10,000 switching cycles and an overvoltage category of III.
The device supports conductor cross-sections from 0.75 mm² to 35 mm² for solid and stranded conductors, with specific limits for finely stranded conductors. It features combined terminals at both the top and bottom and is sealable.
With a protection class of IP20 when connected, the Siemens 5SY4116-5 is built for reliable circuit protection. It is also halogen-free and silicon-free, contributing to environmental considerations in its application.
The rated operational current is 16 A at AC. At elevated temperatures it is derated to 15.23 A at 40 °C, 14.83 A at 45 °C, 14.43 A at 50 °C, 14 A at 55 °C, and 13.57 A at 60 °C.
The rated supply voltage is 400 V AC, with 230 V AC for single-phase operation. The maximum DC operating voltage is 72 V.
It provides 10 kA according to EN 60898, 20 kA according to IEC 60947-2, 15 kA at DC, and 5 kA according to UL 1077 and CSA C22.2 No.235.
The tripping characteristic is Type A.
The breaker measures 90 mm high, 18 mm wide, and 76 mm deep, with 70 mm installation depth. It occupies one modular width unit and mounts on DIN rail using a quick assembly system.
Solid and stranded conductors from 0.75 to 35 mm² can be connected, finely stranded conductors with core end processing from 0.75 to 25 mm², and AWG sizes from 18 to 4.
It complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077.
