For backup fuse coordination, the maximum gL/gG fuse is 50 A at 400 V, 40 A at 500 V, and 35 A at 690 V. No ground fault detection on this variant, so if you need that, you're looking at a different order code.
DIN rail footprint and clearances
Depth is 97 mm, height 97 mm. Mounting position any. Required clearances: 50 mm upwards and downwards, 30 mm to the side, 0 mm forwards and backwards. That 0 mm backwards means it can sit flush against the backplane or a busbar support. The 50 mm top/bottom gap is for arc-gas venting and terminal access — don't crowd it.
