The Siemens 5SY4310-7 is a 3-pole miniature circuit breaker designed for reliable circuit protection in industrial and mechanical engineering applications. It operates with a rated voltage of 400V AC and a rated current of 10A at 35°C, with a C tripping characteristic.
This circuit breaker offers a switching capacity of 10kA according to EN 60898 and 20kA according to IEC 60947-2. It supports a wide range of conductor cross-sections, from 0.75 mm² to 35 mm² for solid and stranded wires, and up to 25 mm² for finely stranded wires with core end processing. The device features combined terminals at both the top and bottom, a quick assembly system for DIN rail mounting, and a mechanical service life of typically 10,000 switching cycles.
Key features include a protection class of IP20 with connected conductors, an insulation voltage of 440V, and it is halogen-free and silicon-free. The compact design with a width of 54mm and installation depth of 70mm makes it suitable for various panel installations. It also supports supplementary devices for extended functionality.
