That flexibility means it fits into tight panel layouts without forcing a specific orientation. Wire range accepts solid or stranded conductors from 1 to 10 mm², and for double ferruled connections it handles 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). That covers most control and power wiring you'll see in a standard industrial panel — no need for special lugs or adapters. ## Switching frequency and thermal limits Maximum switching rates are 1,000 cycles per hour for AC-1 resistive loads, 750 cycles per hour for AC-3 motor starting, and 250 cycles per hour for AC-4 inching/plugging duty. The arcing time is 10 ms, and the coil operates on AC with pick-up times of 4 to 16 ms. For a line-down replacement, these numbers tell you the contactor can keep up with a fast cycling process without overheating the coil or welding the contacts.","metaTitle":"Siemens 3RT2026-1AL20-ZX95 SIRIUS Power Contactor, S0 Size,","metaDescription":"Siemens SIRIUS 3RT2026-1AL20-ZX95 power contactor, S0 size, 45mm width, screw terminals, active production.
