The 5SJ4330-8HG41: Rated current holds at 30 A up to 40 °C ambient; derates to 27 A at 60 °C. Operating range spans -40 to 75 °C, so it handles both cold storage and hot panel environments. Sealable and halogen-free, suitable for controlled environments where outgassing matters.
Three modular width units (54 mm width) snap onto standard mounting rail; any mounting position accepted. Combined terminals top and bottom simplify wiring.
Depth 70 mm, width 54 mm, height 110 mm.
Yes, it mounts on a standard mounting rail (DIN rail) and can be oriented in any position.
