The mechanical life of 30 million operations is typical for this class — the electrical life depends on the switching category (AC-1, AC-3, AC-4), so match the duty cycle to your load type. Main and auxiliary circuits use screw-type terminals; the main terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded — or 2x 12 AWG for the US market. The auxiliary switch extension is supported if you need feedback contacts.","metaTitle":"Siemens 3RT6018-1BF41 SIRIUS Contactor, S00, 110 V coil, 13","metaDescription":"Siemens 3RT6018-1BF41 SIRIUS power contactor, size S00, 110 V AC coil, 13 kW motor rating at 400 V 60°C.
