Integrator's Spec Brief
The coil connection uses spring-type terminals, while the main contacts accept solid or stranded conductors from 0.5 to 4 mm², or 2x (0.5 to 4 mm²) for paralleled feeds.
For motor switching duty (AC-3), the maximum mechanical switching rate is 750 operations per hour, which governs how fast you can cycle a motor start/stop without overheating the contacts. The AC-4 (plugging/reversing) rate drops to 250 operations per hour, reflecting the higher electrical stress of inching or reversing under load. The typical mechanical service life is 30,000,000 operations. An auxiliary switch is included for status feedback.
Spring-type coil terminals reduce wiring time compared to screw terminals — no torque driver needed for the coil circuit. Main contact torque range is 20 to 12 Nm (likely a range for different conductor sizes, though the evidence lists it as a range).
