For AC-1 resistive duty, this contactor handles 156 A at 480 V and 144 A at 600 V — these are the numbers that govern the main power path for heater banks, lighting, or non-inductive loads. The S10 frame keeps the contactor compact at 210 mm high, 145 mm wide, and 202 mm deep, fitting into standard panel layouts with screw fixing. The contactor accepts solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) per terminal. ## Switching Capability and Duty Cycle Beyond the AC-1 ratings, the 3RT1466-6XB46-0LA2 carries DC switching ratings across multiple voltage levels: 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, 6 A at 230 V, 3 A at 400 V, and 2 A at 500 V. These are the DC-1 or DC-3 break currents — critical when the contactor must interrupt DC motor fields, brake coils, or battery circuits where the arc is harder to extinguish than with AC. Maximum operating frequency is 600 operations per hour at AC-1 and 350 operations per hour at DC-1. The arcing time sits between 10 and 15 ms, and the DC break time (at rated control voltage) is 80 to 100 ms — useful for timing coordination in sequential start circuits. Mechanical endurance is typical at 10 million operations, meaning the contactor outlasts most panel designs before a swap is needed. Fastening is via screw fixing through a single 11 mm diameter hole — no DIN-rail adapter on this variant, so plan for a drilled backplate or mounting bracket.","metaTitle":"Siemens 3RT1466-6XB46-0LA2 SIRIUS Contactor, S10, 24 VDC Coi","metaDescription":"Siemens SIRIUS contactor 3RT1466-6XB46-0LA2, size S10, 24 VDC coil, rated 156 A at 480 V AC-1.
