SIRIUS S00 Power Contactor — 3RT2016-1AV01
For AC-3 motor switching duty, the contactor is rated at 750 operations per hour maximum; AC-1 resistive load switching allows up to 1,000 ops/h. The AC-4 maximum is 250 ops/h, reflecting the heavier wear from inching and plugging duty. Arcing time spans 10 to 15 ms at AC, with a total break time of 4 to 15 ms. These figures matter for coordination with upstream protective devices — the arc clears fast enough to avoid nuisance fuse operation in most panel designs. Auxiliary switch is included as standard, simplifying interlocking or status feedback wiring without an add-on block.
Termination and Conductor Sizes
For paralleled conductors, the terminal accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². The coil connection uses screw-type terminals. These are the minimum air gaps to maintain rated insulation — panel wireway planning should respect these, not crowd the contactor against duct or other devices.
Typical mechanical life of the contactor is 30 million operations, per the manufacturer's design target.
