The 2-pole design (2P, 3 width units) fits standard mounting rail and screw fixing. Terminal tunnels top and bottom accept solid or stranded conductors from 0.75 mm² up to 50 mm² (AWG 14 to 2). Halogen-free and silicon-free construction matters in enclosed panels where outgassing from a fault could damage nearby electronics.
Where it lives in the panel
Installation depth is 92 mm. Tightening torque for the screw terminals is 2.5 to 3.5 N·m (22 to 31 lbf·in). The breaker is touch-protected (finger-safe) per the product feature listing.
