The 3RT2025-2BB40: Mounts on a 35 mm DIN rail per EN 60715, either snapped on or screwed. The 45 mm wide body and 102 mm height tuck into tight panels, and the depth of 107 mm leaves room for wiring behind the gland plate.
How it stacks up against a peer
Out here in the grease, if a panel was spec'd around the 3RT2026-1FB44-3MA0, this 3RT2025-2BB40 shares the same S0 frame dimensions — 45 mm wide, 102 mm tall, 107 mm deep — so it'll drop onto the same DIN rail without resizing. But I'd check the coil voltage and auxiliary contact layout before calling it a straight swap; those little differences can trip you up mid-install.
