The 110-127 V AC coil pulls in reliably across that range; the spring-type coil terminals accept solid 2x (0.25-2.5 mm²) or stranded 25-120 mm² power wiring, so it fits both panel pre-wire and field cable. The auxiliary switch is built in, saving a separate add-on block for status feedback or interlocking.
The contactor is rated for 750 switching cycles per hour in AC-3 duty (squirrel-cage motor starting), which is the typical benchmark for conveyor, pump, and fan applications. In AC-1 resistive loads it can manage 800 cycles/hour; AC-4 reversing or plugging duty drops to 130 cycles/hour. The arcing time is 10-15 ms, and the total operating time (coil energization to main contact closure) is 40-60 ms for both AC and DC control circuits.
Fastening is by screw fixing through a single 9 mm hole. The dimensions are 172 mm high, 120 mm wide, and 170 mm deep. This is a panel-mount contactor, not a DIN-rail snap-on — plan for screw-down installation with the specified air gaps for arc quenching and heat dissipation.
