Rated operational current at AC-12 is 10 A; for motor loads, the AC-2 rating at 400 V is 11 kW, and AC-4 at 400 V is 15.5 A. Coil draws 0.8 to 1.1 A at 50 Hz. Main and auxiliary circuits use screw-type terminals. Main contacts accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid; auxiliary contacts accept 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²) solid/stranded, max 2x 10 mm². AWG equivalents: main 2x (16 to 12), 2x (14 to 10), 1x 8; auxiliary 2x (20 to 16), 2x (18 to 14), 1x 12. Side-by-side mounting is permitted — no derating gap required.","metaTitle":"Siemens 3RT1026-1AB00 SIRIUS Power Contactor, 24 V 50 Hz Coi","metaDescription":"Siemens 3RT1026-1AB00 SIRIUS power contactor, 3 NO main contacts, 24 V 50 Hz coil, S0 size, screw terminals.
