D-Curve Miniature Circuit Breaker
The Siemens 5SJ4305-8HG41 is a SENTRON miniature circuit breaker with D tripping characteristic. Pollution degree 3 and overvoltage category 3 suit fixed installations in industrial environments where conductive pollution and transient overvoltages are present. Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s) – relevant for mounting on machinery or in mobile equipment. The 3-pole design occupies three modular width units (54 mm wide) on a standard mounting rail. Installation depth is 70 mm. Ambient temperature range of –40 °C to 75 °C, with humidity up to 95%.
