The auxiliary contact block carries 10 A at 24 VDC, 2 A at 48 V and 60 VDC, and derates to 0.3 A at 220 VDC. For the commissioning engineer: the coil pick-up and drop-out timing sits in the 7–13 ms range at DC, with arcing time between 10–15 ms — consistent with a standard DC-operated contactor for control-panel duty.
The contactor accepts solid or stranded conductors from 0.5 to 4 mm², and can take two conductors per terminal in combinations like 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²).
Operating conditions and switching rates
Maximum switching frequency depends on duty: 1,000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). The mechanical life is typical 30 million operations — a figure that matters for high-cycling applications like conveyor or pump control.
