The 5SY4432-6: Mounting position is any orientation, and the quick-assembly system snaps onto the rail without tools. IP20 with connected conductors — the terminals are touch-protected when wired, but the breaker itself is not sealed against water ingress; install inside a rated enclosure.
Sourced to order against RFQ quantities through independent distribution channels.
The 5SY4432-6 has a depth of 76 mm from the DIN-rail mounting surface to the front of the toggle.
