The contactor measures 45 mm wide by 85 mm tall by 151 mm deep, fitting the S0 envelope. The main contacts are rated for 16 to 8 A depending on the duty cycle — the specific AC-3 motor-switching current isn't listed here, but the frame size and terminal range indicate it handles typical fractional-to-small-horsepower motor loads. ## Duty Cycles and Switching Frequency — What the Ratings Mean The maximum switching frequency varies by duty class: 1,000 operations per hour at AC-1 (resistive loads), 750 per hour at AC-2 and AC-3 (motor starting and running), and 250 per hour at AC-4 (plugging or inching). These are the contactor's thermal limits for the main contacts — exceeding them shortens electrical life or risks contact welding. For a conveyor drive running continuous AC-3 duty, 750 ops/h is generous; for a press that cycles at 300 ops/h in AC-4, the 250 ops/h ceiling is the binding constraint. The DC coil operates with a dropout time of 15 to 17.5 ms, which matters for sequencing logic where you need predictable de-energization timing. ## Environmental Limits and Mounting Position","metaTitle":"Siemens 3RT2026-1FB48-0GS2 SIRIUS Power Contactor, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT2026-1FB48-0GS2 power contactor. 24 VDC coil, S0 frame, screw terminals.
