The Siemens 5SY4313-7 is a 3-pole miniature circuit breaker designed for industrial applications. It operates with a rated supply voltage of 400V AC and has an operational current rating of 13A at 35°C, with derating at higher temperatures.
This circuit breaker features a C-curve tripping characteristic, making it suitable for protecting circuits with moderate inrush currents. It offers a switching capacity of 10kA according to EN 60898 and up to 20kA according to IEC 60947-2. The device is rated for an overvoltage category of III and has a degree of pollution of 3.
Designed for mechanical engineering and industrial use, the 5SY4313-7 is halogen-free and sealable. It mounts on a DIN rail and has a width of 54mm, corresponding to 3 modular width units. The terminals accept conductor cross-sections from 0.75 mm² to 35 mm² (solid/stranded) and require a tightening torque between 2.5 N·m and 3.5 N·m.
Key technical data includes an insulation voltage (Ui) of 440V AC and a maximum DC operating voltage of 72V. The power loss per pole at rated current and hot operating state is 1.4W. The mechanical service life is typically 10,000 switching cycles.
