AC-1 resistive load rating reaches 40 A at 400 V. Maximum switching frequency varies by duty: 1000 cycles/hour for AC-1, 750 cycles/hour for AC-2 and AC-3, and 250 cycles/hour for AC-4 (plugging or inching). The AC-3e rating matches the standard AC-3 figure at 750 cycles/hour. The S0 frame occupies 45 mm width on the rail. ## Environmental limits","metaTitle":"Siemens 3RT2026-1AD00 SIRIUS Power Contactor, S0 Frame, 24 V","metaDescription":"Siemens SIRIUS 3RT2026-1AD00 power contactor, S0 frame, 24 VDC coil, screw terminals.
