Key ratings for the buyer's decision
Wire capacity is solid or stranded 1 to 10 mm² on the main contacts, with the coil terminals accepting 2x (0.5 to 2.5 mm²) solid or stranded. That covers standard motor and control wiring without needing adapter lugs. Rated for 1 000 operating cycles per hour in AC-1, AC-2, AC-3, and AC-3e duty, dropping to 300 cycles per hour in AC-4. That's a solid industrial spec — fine for unheated plant floors and most outdoor cabinets in temperate climates. That helps when you're squeezing it into a tight panel layout.
That's tight enough for dense panels but leaves room for wiring fingers and heat dissipation.
