Side-by-side mounting is permitted with no derating gaps, saving rail space in dense control panels. ## Motor ratings and coordination AC-3 switching current is 12.5 A at 400 V, supporting the 7.5 kW motor rating at 690 V. For reversing or plugging duty (AC-4), the same 12.5 A applies — this contactor handles the full motor current in both directions without derating the main poles. Type 2 coordination (no weld after fault) requires a 25 A gL/gG fuse upstream; Type 1 coordination (welding allowed but no fire) uses a 63 A gL/gG fuse. Screw terminals accept solid or stranded wire: main contacts take 2x (1–2.5 mm²) or 2x (2.5–6 mm²), max 2x 10 mm²; auxiliary contacts take 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²), max 2x 4 mm². AWG equivalents: main 2x (16–12) or 2x (14–10), max 1x 8; auxiliary 2x (20–16) or 2x (18–14), max 1x 12.
