The AC-3e maximum switching rate is 750 operations per hour, with a mechanical life of 30 million operations typical — figures that govern replacement intervals in high-cycling applications like conveyor or pump control. The screw-type main circuit terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded conductors. Minimum permissible cross-section at 40 °C is 4 mm², at 60 °C is 2.5 mm² — important for sizing field wiring under elevated ambient conditions.","metaTitle":"Siemens 3RT6016-1AN21 SIRIUS Power Contactor, S00, 7.5 kW at","metaDescription":"Siemens 3RT6016-1AN21 SIRIUS power contactor, size S00, 45 mm wide, 73 mm deep.
