The Siemens 5SJ4311-8HG41 is a SENTRON 3-pole miniature circuit breaker with a D tripping characteristic, designed for 400 V AC / 60 V DC circuits at 50 Hz.
Vibration resistance: 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 sec). Sealable, halogen-free, silicon-free. Suitability noted for mechanical engineering and industry applications.
Both are 3-pole Siemens MCBs on the same DIN-rail footprint, but the 5SY4140-7 is a different series with a C characteristic. The 5SJ4311-8HG41 uses a D curve, so it will physically fit the same rail space but the trip characteristic differs — verify coordination with downstream loads before swapping.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
