The 3RF3350-1AA14 is a 1-pole SIRIUS 3RF33 solid-state contactor rated 50 A in AC-1 duty at 40 °C. AC-1 covers resistive and slightly inductive loads — heaters, ovens, lighting banks. For motor starting (AC-3), the usable current will be lower; the part does not carry a published AC-3 rating in this listing, so size it against your actual load type, not the headline number. The load circuit accepts 48-460 V AC, and the control coil is 24 V AC/DC, screw-terminated.
