Rated 105 A — what that means for motor duty
The A75-30-00-84: The 105 A rating is the conventional free-air thermal current (Ith) at 600 VAC. For AC-3 motor switching (starting and stopping squirrel-cage motors), the contactor is typically applied at about 50–60 % of Ith — roughly 50–65 A motor full-load current — depending on the utilization category. The 110 VDC coil voltage is for DC control circuits, not the main power.
3-pole, DIN rail, no auxiliaries
Three main poles, non-reversing, with no built-in auxiliary contacts — if you need N.O./N.C. feedback for the PLC or status lamp, add a side-mount auxiliary contact block. The DIN rail footprint snaps onto standard 35 mm rail; panel layout is straightforward for a 105 A frame.
