This Siemens 5SJ4 miniature circuit breaker is a 2-pole device designed for reliable circuit protection in industrial and mechanical engineering applications. It features a D-trip characteristic and a rated operational current of 16A at 30°C, with derating at higher temperatures.
The breaker operates at a rated supply voltage of 400V AC and has a maximum AC operating voltage of 240V according to UL 489 and CSA C22.2 No. 5-02 standards. It provides a switching capacity current of 10 kA according to EN 60898 and 15 kA according to IEC 60947-2. The short circuit breaking capacity is 14 kA at AC.
With a mechanical service life of typically 10,000 switching cycles, this circuit breaker is built for durability. It has a compact design with a width of 36mm and a depth of 70mm, suitable for DIN rail mounting. The device offers touch protection and is sealable. It also supports the installation of supplementary devices.
Environmental considerations include halogen-free and silicon-free construction. The protection class is IP20 with connected conductors and IP40 in the handle range. It is suitable for environment B regarding EMC.
