The AF146B-30-22RT-12 is an IEC contactor rated 225 A at 600 VAC, with a 48-130 VAC control coil and a 3-pole configuration. It carries a 125 HP motor rating and includes 2 normally open and 2 normally closed auxiliary contacts. The 225 A rating is the continuous current in AC-1 duty — for motor loads (AC-3), derate to the listed horsepower, which lands around 125 HP on 460 V.
Integration Notes
The 48-130 VAC control coil range means it can be driven directly from a control transformer tap without an intermediate relay — useful in panels where the control voltage varies or needs to be field-switched. The 2NO/2NC auxiliary block is built in, so no separate add-on needed for basic feedback or interlock.
