The Siemens 5SL4232-7RC is a SENTRON miniature circuit breaker (MCB) — two-pole, C-curve, rated 32 A with a 10 kA breaking capacity per EN 60898 at 415 V AC. Mounting position is any, which helps when you're cramming breakers into a tight enclosure.
Depth is 76 mm, height 90 mm, and the installation depth (including terminals) is 70 mm. That's the same footprint as the 3-pole 5SL4363-7, so if you're swapping a 3-pole for two 2-poles or vice versa, the rail position and enclosure depth don't change. The 18 mm width per pole is standard — no surprises when laying out a multi-way board.
