This Siemens 5SJ4 miniature circuit breaker is a 2-pole device with a tripping characteristic class C. It is rated for a 30A operational current at AC and has an operating voltage of up to 240V AC according to UL 489 and CSA C22.2 No. 5-02.
The breaker features a switching capacity of 10 kA according to EN 60898 and 15 kA according to IEC 60947-2. It has a short circuit breaking capacity of 14 kA at AC according to UL 1077 and CSA C22.2 No.235. The device is suitable for mechanical engineering and industrial environments.
With a mechanical service life of typically 10,000 switching cycles, this circuit breaker is built for durability. It has a protection class of IP20 with connected conductors and IP40 in the handle range. The unit dimensions are 110 mm in height, 36 mm in width, and 70 mm in depth, with an installation depth of 70 mm. It mounts on a standard DIN rail.
Additional features include touch protection, halogen-free construction, and sealability. It supports connectable conductor cross-sections from 0.75 mm² to 25 mm² with core end processing, and has a maximum tightening torque of 3.5 N·m for screw-type terminals.
The operating voltage is 240 V AC maximum (UL 489/CSA C22.2) and 400 V AC rated (IEC). For DC, maximum 60 V (single channel) or 125 V (2-channel).
