The Siemens 5SJ4160-8HG41 is a 1-pole SENTRON miniature circuit breaker (MCB) from the 5SJ4 series, with a D tripping characteristic and a rated current of 60 A at both 30 °C and 40 °C ambient. Its 18 mm width (1 modular unit) and snap-on mounting to standard DIN rail mean it fits directly into any 5SJ4 distribution board or panel without adapters.
While the breaker is rated 60 A at up to 40 °C, the continuous current must be derated above that: 58.2 A at 45 °C, 56.4 A at 50 °C, 54.4 A at 55 °C, and 52.8 A at 60 °C.
Installation depth is 70 mm from the rail — measure your enclosure depth before committing. IP20 with connected conductors; IP40 in the handle range.
Vibration resistance: 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4-second dwell) — suitable for machinery-mounted panels.
