The solid-state design means no moving contacts to wear out, and power dissipation is low: 0.05 W at AC in hot operating state, so it won't cook adjacent components in a dense panel. Terminals accept solid conductors from 0.5 to 4 mm², or 2x (0.5 to 2.5 mm²) — fine for standard motor leads up to about 4 mm². The screw-type main current circuit is familiar to any panel builder; no special tooling needed. Shock resistance of 15g / 11 ms means it holds up on vibrating conveyor drives.
Carries ATEX protection type PTB 06 ATEX 3001 Ex II (2) GD, so it's rated for use in potentially explosive atmospheres (Zone 2 gas, Zone 22 dust) when paired with an appropriate contactor. Surge voltage resistance is 6 kV, and burst immunity meets IEC 61000-4-4 severity level 3 — 2 kV on power ports, 1 kV on signal ports. That covers most industrial EMC environments without external filtering.
