The mechanical switching frequency hits 1 000 operations per hour under AC-1, AC-2, AC-3, and AC-3e duty, and 300 ops/h under AC-4. That 1 000 ops/h in AC-3 (motor starting) is the figure that governs conveyor or pump cycling — if your application needs faster cycling, this contactor will not sustain it. DC switching capacity is derated by voltage: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. For a 125 VDC solenoid or brake circuit, the 0.9 A limit is the one that decides fit — not the AC rating. The coil operates across -25 to +60 °C ambient, with storage range from -55 to +80 °C. That -25 °C floor means it is not rated for freezer or arctic outdoor installation without a heated enclosure. Wire range accepts solid or stranded 1 to 10 mm² on the main contacts, and 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) on auxiliary contacts. That covers standard motor leads up to about 4 mm² for a 4 kW motor; larger loads need a bigger contactor frame.
Dimensions: 85 mm high, 45 mm wide, 107 mm deep. That 6 mm side gap is tighter than the vertical ones; plan terminal access accordingly.
