5SJ4102-8HG41

The Siemens 5SJ4102-8HG41 is a 1-pole miniature circuit breaker from the 5SJ4 series, suitable for mechanical engineering and industrial applications. It operates with a rated supply voltage of 400V AC and has a maximum operating voltage of 240V AC according to UL 489 and CSA C22.2 No. 5-02 standards. The breaker offers a switching capacity of 10 kA according to EN 60898 and 15 kA according to IEC 60947-2, with a short circuit breaking capacity of 14 kA.

This device features a D-trip characteristic and a rated operational current of 2A at 30°C and 40°C, with slightly reduced ratings at higher temperatures. It has an insulation voltage of 440V AC and is designed for DIN rail mounting with a width of 18mm (1 modular width unit). The protection class is IP20 with connected conductors and IP40 in the handle range. The breaker is halogen-free, sealable, and silicon-free, with a mechanical service life of typically 10,000 switching cycles.

Connections are made via combined terminals, and it supports finely stranded conductors with core end processing from 0.75 mm² to 25 mm². The tightening torque for screw-type terminals is a maximum of 3.5 N·m. The overall dimensions are 110mm height, 18mm width, and 70mm depth, with an installation depth of 70mm. It is suitable for environments with immunity to interference not applicable (Environment B) and has an overvoltage category of 3 and degree of pollution of 3.
