It's a 3-pole (3P) contactor rated for AC-3 duty at 12 A up to 440 V — that's the motor-switching rating, meaning it handles the inrush of a small three-phase motor and breaks the load current under running conditions. The coil is 48 V DC, so it pulls in cleanly on a DC control supply; the IP20 finger-safe terminals mean it's panel-mount ready without extra shrouding.
The headline number is AC-3 12 A at 440 V — that's the motor load it can switch reliably. AC-3 covers starting and plugging of squirrel-cage motors; the same contactor also carries AC-1 (resistive load) and AC-4 (inching/plugging) ratings, though those aren't quantified in the brief spec. The V1 flame retardance per UL 94 means the housing won't propagate a fire if a fault arc hits it.
The preassembled reversing busbar saves you the wiring of the interlock and the phase-reversal connections; just land your motor leads and control wires.
