The Siemens 5SY4603-8 is a miniature circuit breaker designed for robust protection in industrial and mechanical engineering applications. This 4-pole device, featuring a 3P+N configuration, operates on AC voltage with a rated supply voltage of 400V and an insulation voltage of 440V.
Key electrical specifications include a 3A operational current rating at 35°C, a D-tripping characteristic, and a switching capacity of 10kA according to EN 60898. It also offers a breaking capacity of 15kA at DC and 35kA at AC according to IEC 60947-2. The breaker is suitable for conductor cross-sections ranging from 0.75 mm² to 35 mm² for solid and stranded wires.
Mechanically, the 5SY4603-8 is designed for DIN rail mounting with a quick assembly system. It has dimensions of 90mm height, 72mm width, and 76mm depth, with an installation depth of 70mm. The device is rated IP20 with connected conductors and supports features like neutral conductor switching and sealability.
Environmental considerations include a degree of pollution of 3 and compliance with standards such as IEC/EN 60898-1 and IEC/EN 60947-2. The product is also noted as halogen-free and silicon-free.
