At 32 A, it's sized for a 3-phase subfeed or a large single-phase load. The 4-pole design (all poles switched) is common in North American and IEC panels where you need to break all lines including neutral. Temperature derating is published: at 35 °C it carries the full 32 A; at 40 °C it's 30.72 A; at 50 °C it's 29.41 A; and at 60 °C it's 28.03 A.
Mounting position is any, which helps in tight enclosures. The breaker is 4 modular width units wide (72 mm), 90 mm tall, and 76 mm deep (70 mm installation depth behind the panel surface). Sealable, halogen-free, silicon-free — good for clean-room or food-adjacent panels where outgassing matters. Touch protection is built in.
