The AC-3e rating also allows 200 ops/h. These limits govern how often the contactor can be cycled without exceeding thermal rise — for a high-cycle application like a stamping press or indexing conveyor, the AC-4 ceiling of 130 ops/h is the binding constraint, not the AC-3 figure. The contactor measures 160 mm wide, 225 mm deep, and 214 mm high — size S12 frame. Conductor cross-sections accepted range from 70 to 240 mm² stranded for main power, with auxiliary terminals accepting 0.5 to 4 mm² solid or stranded.","metaTitle":"Siemens 3RT1076-6SP36-3PA0 SIRIUS Power Contactor, Size S12,","metaDescription":"Siemens SIRIUS power contactor 3RT1076-6SP36-3PA0, size S12, 200-277V AC coil, screw terminals.
