The 32 A rating is at 40 °C ambient; note the derating curve above that — at 50 °C it's 28.9 A, at 60 °C it's 27.2 A. If your panel runs hot, size up one frame.
Occupies 4 modular width units at 72 mm wide. Any mounting position allowed. Halogen-free and silicon-free — important if the panel shares space with sensitive contacts or optics.
4-pole C-curve MCB rated 32 A at 40 °C, breaking capacity 10 kA per EN 60898, IP20 with conductors, operating temperature -40 to 75 °C.

The 5SY4432-7CC11 is a 4-pole, 32 A C-curve MCB in a 72 mm wide housing. The 5SY6332-7CC is also a 4-pole C-curve MCB but with a different breaking capacity and possibly a different depth — verify the panel's DIN-rail layout and conductor length before swapping without rewiring.
