The Siemens 5SJ6106-6 is a 1-pole SENTRON miniature circuit breaker with a B-curve trip characteristic, rated 6 A at 240 V AC and 60 V DC, with a 6 kA breaking capacity per both IEC 60898 and IEC 60947-2. The B-curve means it trips between 3 and 5 times rated current — suited for resistive or general-purpose loads where inrush is modest, not for motor starting or transformer primaries that draw a higher surge. The 6 kA SCCR at 240 V AC covers most commercial and light industrial panelboards; if your fault current runs higher, you'd need a higher-rated upstream device. At 18 mm wide (one modular unit), it snaps onto a standard DIN rail and occupies a single slot in a distribution board. The 76 mm depth (70 mm installation depth) leaves clearance for wiring in a shallow enclosure. Mounting position is any, which simplifies panel layout — no derating required for horizontal or inverted installation.
Compliance & Environment
Rated for overvoltage category III and pollution degree 2, which covers fixed-installation distribution boards in dry, non-conductive environments. IP20 with connected conductors — fine inside a closed panel, not for wet or dusty locations. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in a sealed enclosure. The mechanical service life is 20,000 switching cycles typical.
