This Siemens 5SY4203-7 is a 2-pole miniature circuit breaker designed for reliable circuit protection. It operates with a rated current of 3A and a voltage rating of 400V AC, suitable for various industrial and mechanical engineering applications.
The breaker utilizes a Type C tripping characteristic, providing protection against overcurrents and short circuits. It offers a significant switching capacity of 10kA according to EN 60898 standards and 15kA at DC according to IEC 60947-2. The device is built for a mechanical service life of 10,000 switching cycles.
Designed for DIN rail mounting, this circuit breaker has a width of 36mm, corresponding to 2 modular width units. It supports conductor cross-sections from 0.75mm² to 35mm² for solid and stranded wires, and up to 25mm² for finely stranded wires with core end processing. The protection class is IP20 with connected conductors.
Additional features include halogen-free construction and sealability. The breaker is suitable for use in environments with a pollution degree of 3 and an overvoltage category of III.
