This Siemens 5SJ4103-8HG41 is a 1-pole miniature circuit breaker from the 5SJ4 series. It is designed for industrial and mechanical engineering applications and mounts on a standard DIN rail.
The breaker operates with a tripping characteristic class D and has a rated operational current of 3A at AC. It supports a maximum AC operating voltage of 240V according to UL 489 and CSA C22.2 No. 5-02, and a rated supply voltage of 400V AC at 50Hz. The short circuit breaking capacity is 10kA according to EN 60898 and 15kA according to IEC 60947-2, with a breaking capacity of 14kA according to UL 1077 and CSA C22.2 No.235.
Key electrical features include an insulation voltage of 440V AC and a power loss of 1.8W per pole. It is suitable for connecting conductor cross-sections ranging 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.
Mechanically, the unit measures 110mm in height, 18mm in width, and 70mm in depth, with an installation depth of 70mm. It has a net weight of 171g. The breaker is rated IP20 with connected conductors and IP40 in the handle range. It also features touch protection and is halogen-free, sealable, and silicon-free.
