Rated current holds at 30 A up to 40 °C ambient; above that it derates to 29.1 A at 45 °C, 28.2 A at 50 °C, 27.2 A at 55 °C, and 26.4 A at 60 °C — factor that into your thermal layout if the panel runs warm.
IP20 with connected conductors, IP40 in the handle range. Vibration resistance: 50 m/s² at 25 to 150 Hz and 60 m/s² at 35 Hz (4 s).
No official successor is listed; the 5SJ4 series remains the current SENTRON miniature breaker line for 1-pole C-curve 30 A applications.
Single-pole, C-curve, 30 A rated current at 400 V AC (holds to 40 °C ambient). Derates above 40 °C: 29.1 A at 45 °C, 28.2 A at 50 °C, 27.2 A at 55 °C, 26.4 A at 60 °C.
Width 18 mm (1 modular unit), height 110 mm, depth 70 mm. Snaps onto a standard DIN rail in any position. Combined terminals top and bottom.
