The main contacts accept solid or stranded conductors from 1 to 10 mm², and the spring-type coil terminals accept dual conductors 2x (0.5 to 2.5 mm²). No auxiliary switch is fitted on this variant, so any auxiliary contact block must be ordered separately and added to the front or side of the contactor. ## Duty Cycle and Switching Ratings This contactor is rated for motor switching up to 3 hp at 230 V (per). For resistive loads (AC-1), the maximum switching rate is 1,000 operations per hour; for motor loads under AC-3 or AC-3e duty, the maximum is 750 ops/h. For the most demanding AC-4 duty (plugging, inching), the rate drops to 250 ops/h. The typical mechanical life is 10,000,000 operations, so the contactor is designed for high-cycle applications when operated within these limits. Switching current ratings are specified per voltage: 6 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.6 A at 440 V. The arcing time at AC is 4 to 16 ms. Coil holding power is 0.25 VA at 50 Hz and 0.28 VA at 60 Hz. ## Environmental and Lifecycle Status The 3RT2026-2CK64-3MA0 is in the current lifecycle stage per the manufacturer. For audit purposes, the datasheet and compliance documentation (RoHS, REACH, relevant IEC/UL standards) are available from the manufacturer upon request — this part is a standard catalog item, not a special or phased-out variant.","metaTitle":"Siemens SIRIUS 3RT2026-2CK64-3MA0 Power Contactor, Size S0,","metaDescription":"Siemens SIRIUS 3RT2026-2CK64-3MA0 power contactor, size S0, 45 mm width, spring-type terminals, screw and snap-on DIN rail mounting.
