5SY4620-6

This Siemens 5SY4620-6 is a miniature circuit breaker designed for robust protection in industrial and mechanical engineering applications. It features a 4-pole configuration with a 3P+N design, suitable for AC power systems with a rated supply voltage of 400V and a frequency range of 50/60 Hz.

The breaker offers a tripping characteristic class B and a significant switching capacity of 10kA according to EN 60898, with higher ratings under IEC standards. It is designed for DIN rail mounting with a quick assembly system, and its dimensions are 90mm in height, 72mm in width, and 76mm in depth, with an installation depth of 70mm.

Key features include a mechanical service life of 10,000 switching cycles, overvoltage category III, and degree of pollution 3. The operational current is rated at 20A at 35°C, with derated values at higher temperatures. It supports a wide range of conductor cross-sections from 0.75 mm² to 35 mm² for solid and stranded conductors, and up to 25 mm² for finely stranded conductors with core end processing. The terminals require a tightening torque between 2.5-3.5 N·m (22-31 lbf·in).

Additional product features include halogen-free and silicon-free construction, sealability, and the capability for installing supplementary devices. It meets various international standards including IEC/EN 60898-1 and IEC/EN 60947-2.
