The 24 VAC coil operates at both 50 Hz and 60 Hz, with a tolerance range of 0.8...1.1 times rated voltage at 50 Hz and 0.85...1.1 at 60 Hz. Solid wire acceptance: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max. 2x (0.75...4 mm²). Stranded wire acceptance: 2x (1...2.5 mm²), 2x (2.5...6 mm²), max. 2x 10 mm². AWG equivalents for main contacts: 2x (16...12), 2x (14...10), 1x 8. The contactor has 2 instantaneous contacts (no auxiliary contact block included). ## Environmental and coordination Maximum operating altitude: 2,000 m. For Type 1 coordination, the required fuse is gL/gG 100 A; for Type 2 coordination, gL/gG 35 A. Mechanical life is typical 10,000,000 operations.","metaTitle":"Siemens 3RT1026-1AC24 SIRIUS Power Contactor, 24 VAC Coil, 1","metaDescription":"Siemens 3RT1026-1AC24 SIRIUS power contactor, size S0, 24 VAC 50/60 Hz coil, 11 kW at 690 V AC-3, screw terminals, IP20 front, DIN rail mount.
