5SY4603-7 Description

Short technical summary and product information.

The Siemens 5SY4603-7 is a miniature circuit breaker with a 4-pole configuration, including a neutral conductor. It is rated for a supply voltage of 400V AC at 50/60 Hz and an operational current of 3A at 35°C, with derating at higher temperatures.

 

This circuit breaker features a C-curve tripping characteristic, suitable for protecting electrical circuits against overloads and short circuits. It offers a switching capacity of 10kA according to EN 60898 and 35kA according to IEC 60947-2. The device has an insulation voltage rating of 440V AC and an overvoltage category of III.

 

Designed for mechanical engineering and industrial applications, the 5SY4603-7 has a mechanical service life of 10,000 switching cycles. It mounts on a DIN rail with a quick assembly system and has dimensions of 90mm height, 72mm width, and 76mm depth, with an installation depth of 70mm. The protection class is IP20 with connected conductors.

 

Additional features include sealability, halogen-free construction, and the ability to install supplementary devices. It supports solid, stranded, and finely stranded conductors with core end processing, with connection cross-sections ranging from 0.75 mm² to 35 mm² (or 25 mm² for finely stranded).
