Lifecycle and compliance — still a current-production part

Mounting and wiring details for the panel builder

That covers most cabinet layouts without forcing a special bracket. Main circuit terminals accept 2x (0.75 to 16 mm²) solid or stranded wire, or 2x (18 to 2 AWG). The minimum permissible cross-section at 40 °C and at 60 °C is 16 mm² — that's the same, so no derating for temperature on the wire size. Control circuit terminals are also screw type, same wire range.
