The 24 VDC coil draws 6 A at rated value — that's the inrush to plan for in your 24 VDC supply loop. Spring-type terminals on the coil side accept 1 … 10 mm² solid or stranded, or 2x (0.5 … 2.5 mm²) for daisy-chaining. Main contacts accept 18 to 8 AWG, so it handles typical motor-circuit wiring without adapters. That's the minimum air gap to maintain around the contactor for arc flash and heat dissipation — factor it into your gland-plate and wireway layout.
Duty-cycle and switching reality
Maximum switching frequency varies by duty: 1 000 ops/h for AC-1 (resistive loads), 750 ops/h for AC-2 and AC-3 (motor starting/running), and 250 ops/h for AC-4 (plugging/inching). The arcing time sits at 10 … 10 ms, and the AC switching time is 4 … 16 ms — consistent for a contactor this size. Coil holding power: 0.25 VA at 50 Hz, 0.28 VA at 60 Hz. That's low enough to run off a small 24 VDC supply without a separate contactor driver.
