At 45 mm wide and 121 mm deep, it fits the standard S00 footprint. ## Switching ratings and operating cycle limits Rated operational current for the main contacts is 20 A at 12 V (AC-1 resistive load curve). The contactor handles 1 000 operating cycles per hour at AC-1 maximum, 750 cycles per hour at AC-3 motor duty, and 250 cycles per hour at AC-4 (high-inrush plugging/reversing). If your application runs frequent jogging or reversing, that 250 cycles/hour ceiling is the hard limit — exceeding it cooks the arc chamber. The coil holds at 0.8 of rated voltage (88 V AC for this 110 V coil) and picks up at 1.1 times rated (121 V). That 1.1 full-scale pickup means marginal voltage drops on a long cable run can cause chatter — keep the feed tight. ## Panel integration and clearances That 6 mm side gap is tighter than the vertical clearances — if you're stacking contactors side-by-side on the DIN rail, leave at least a finger's width between them for heat dissipation.","metaTitle":"Siemens 3RT2015-2BF48-3MA4 SIRIUS Power Contactor, Size S00,","metaDescription":"Siemens SIRIUS 3RT2015-2BF48-3MA4 power contactor, Size S00 frame, 110 V AC coil, spring-type terminals, 45 mm wide.
