The Siemens SENTRON 5SJ6301-7 is a 3-pole miniature circuit breaker with a C tripping characteristic, rated at 1 A and 400 V AC, with a 6 kA breaking capacity per EN 60898. The 1 A rating is the load-side limit; spec it into a circuit where the downstream draw stays under that continuous figure.
Deployment context
Snaps onto a DIN rail. Occupies 3 width units. IP20 with connected conductors; keep inside a sealed cabinet. Any mounting position allowed.
Additional specifications for qualification
The breaker accepts conductors from 1.5 mm² minimum to 2.5 mm² maximum, which covers standard 1.5 mm² lighting circuits and 2.5 mm² small-power circuits. It is halogen-free and silicon-free, so it won't outgas corrosive compounds in a sealed panel — relevant for environments where contact corrosion matters. The vibration resistance is rated at 50 m/s² from 25 to 150 Hz and 60 m/s² from 10 to 150 Hz per IEC 60068-2-6, making it suitable for installation on machinery or in transport applications where vibration is present. Mechanical service life is 20 000 switching cycles typical.
