The 24 VDC coil pulls 6 A inrush and holds at the same nominal voltage, so your control transformer or DC supply needs to deliver that peak without droop. The main contact screw torque range is 16 to 8 Nm. ## Duty ratings and switching frequency Switching frequency depends on the load category. For AC-1 (resistive loads) it can cycle up to 1 000 operations per hour. For AC-2 and AC-3 (slip-ring and squirrel-cage motors) the limit is 750 operations per hour. For AC-4 (plugging / inching) it drops to 250 operations per hour — the arcing time of 10 to 10 ms and DC break time of 15 to 17.5 ms tell you the contactor is designed for moderate switching speeds, not high-cycle servo applications.","metaTitle":"Siemens SIRIUS 3RT2026-1FB48-0ME1-ZX95 Power Contactor, S0,","metaDescription":"Siemens SIRIUS 3RT2026-1FB48-0ME1-ZX95 power contactor, size S0, 24 VDC coil, 21 A rated at 480 V AC-3.
