The coil accepts 23-26 V AC/DC and uses screw-type terminals, so it matches existing 24 V control circuits with a tolerance band for line drop. Rated mechanical life is 10,000,000 cycles, which covers high-duty applications like conveyor or pump cycling without early replacement.
The main power circuit accepts stranded conductors from 25 to 120 mm²; the coil and auxiliary wiring handle solid or stranded from 0.5 to 4 mm² (2 conductors per terminal).
Switching frequency varies by duty: up to 800 cycles/h for resistive loads (AC-1), 750 cycles/h for motor starting (AC-3 and AC-3e), 300 cycles/h for slip-ring motor reversing (AC-2), and 130 cycles/h for plugging/inching (AC-4). Operating time is 40-60 ms on both AC and DC, with an arcing time of 10-15 ms.
