This Siemens 5SY4104-5 is a 1-pole miniature circuit breaker designed for electrical protection. It operates with a rated current of 4A at AC and has a voltage rating of 400V.
The breaker features a Type A tripping characteristic, suitable for general-purpose applications. It offers a switching capacity of 10kA according to EN 60898 and 35kA according to IEC 60947-2. The device is designed for DIN rail mounting and has a mechanical service life of 10,000 switching cycles.
With an IP20 protection class when connected, this circuit breaker is built for industrial environments, including mechanical engineering. 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 tightening torque for screw terminals ranges from 2.5 to 3.5 N·m.
Additional features include halogen-free construction and sealability. The unit dimensions are 90mm height, 18mm width, and 76mm depth, with an installation depth of 70mm.
Rated voltage is 400V AC. Insulation voltage is 440V. Supply voltage is 230V single-phase or 400V multi-phase.
