The main contact configuration is three normally open poles with zero normally closed poles, so any auxiliary NC function must be provided by an external block. This distinction matters for panel builders who must document SCCR and selectivity per IEC 60947-4-1. The 45 mm width and 85 mm height fit the S0 footprint, common across the SIRIUS contactor family. ## Environmental and Wiring Specifications Main circuit terminals accept screw-type connections: solid or stranded conductors from 2x (0.25... 2.5 mm²) up to a maximum of 2x 10 mm², or AWG equivalents of 2x (16... 12) to 1x 8. ## Sourcing and Procurement Note As an active-production part, the 3RT1026-3AV60 is sourced through standard Siemens distribution channels. Procurement should verify that the specific project requires the 3RT1026-3AV60 variant (screw terminals, 3-pole NO, size S0) rather than a similar frame size or terminal type, as the SIRIUS family includes multiple variants with different auxiliary contact configurations and coil voltages.","metaTitle":"Siemens 3RT1026-3AV60 SIRIUS Power Contactor, 11 kW AC-2","metaDescription":"Siemens SIRIUS 3RT1026-3AV60 power contactor, size S0, 3-pole NO, 11 kW at 400 V AC-2, 15.5 A AC-4.
