The front face is IP40 rated, so it's fine for enclosed panel mounting where tools or fingers are the main concern, not washdown.
Thermal derating — 100 A at 45 °C, 91 A at 70 °C
At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A.
Mounting dimensions — fits standard panel cutouts
The 4-pole width (101.6 mm) is a standard 4-module MCCB footprint — it drops into the same cutout as other 4-pole SENTRON 3VA frames. Panel builders can lay out the backpanel with standard DIN-rail or screw-mounting hardware; the depth (70 mm) leaves clearance for rear-connected busbars or cable lugs.
