Integrator's note on the 3RT2016-1AN61
The switching frequency varies by duty: up to 1000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-2 and AC-3 (motor starting/running), and 250 cycles/hour at AC-4 (plugging/reversing). For a line-down replacement, the wire range accepts solid or stranded conductors from 0.5 to 4 mm², including dual conductors up to 2x 2.5 mm² — common for panel wiring. The auxiliary switch is included, with main contact options between 20 and 12 (likely referring to contact configuration).
