Key ratings and what they mean for your panel
The main contacts are rated for 20 A (AC-1) through 12 A (AC-3) — the AC-3 figure is the one that governs motor switching; the AC-1 number applies for resistive loads like heaters. Switching frequency tops out at 750 cycles per hour for AC-3 duty, and 250 for AC-4 (plugging/reversing). If you're cycling a conveyor reverser faster than that, you'll need a larger frame or a dedicated reversing contactor pair. Coil pickup is at 0.8 x rated voltage, dropout at 1.1 x rated voltage. The coil uses screw-type terminals. Auxiliary contacts are present (one N.O. + one N.C. built in), rated for 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, and 0.3 A at 220 V. That covers feedback to a PLC input or holding circuit on the coil. Wire range: solid or stranded 0.5 to 4 mm² (20 to 12 AWG), and it accepts two conductors per clamp in certain combinations (2x 0.5-1.5 mm², 2x 0.75-2.5 mm², or 2x 4 mm²). That's handy for daisy-chaining control power without extra terminals.
Where it goes and how it lives in the panel
Clearance distances: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm to the side. That's tight enough that you can stack contactors side-by-side on the same DIN rail without extra spacing, as long as you respect the 6 mm side gap. Operating temperature is -25 to +60 °C, storage from -55 to +80 °C — fine for most indoor panel environments, including unheated warehouses. Mechanical life is rated at 30 million cycles typical, so this contactor will outlast most of the machinery it controls under normal switching frequencies. The arcing time is 10-15 ms, and DC dropout is 7-13 ms — fast enough for most interlocking circuits.
