Panel fit and mounting flexibility
The 3RT1066-2XJ46-0LA2: The S10 frame contactor measures 202 mm deep, 145 mm wide, and 210 mm tall — dimensions that define the panel cutout and enclosure depth needed for installation. Screw fixing through a single 11 mm diameter hole, torqued to 1.25 Nm, secures the contactor to the backplate.
Switching duty and mechanical endurance
Maximum switching rates vary by duty class: 700 operations/hour in AC-1 (resistive), 500/h in AC-3 (motor starting), 250/h in AC-2 and DC-3/DC-5, 130/h in AC-4 (plugging/inching), and 350/h in DC-1. Typical mechanical endurance is 10 million cycles — this is the contactor body life before contact wear becomes the limiting factor in high-cycle applications. Arcing time of 10–15 ms affects coordination with upstream short-circuit protection devices; factor this into the selective coordination study.
