The ABB AF30ZR-30-02-23 is a 3-pole reversing contactor rated at 32.2 A, with a low-consumption coil accepting 100-250 VAC/DC and two normally-closed auxiliary contacts. The 32.2 A rating is the thermal current (Ith) — the continuous current the main poles can carry in open air — so for motor starting duty (AC-3) you'd typically derate to around 18-22 A depending on the motor's locked-rotor current. The low-consumption coil (LOW designation) means the coil draw is under 5 VA / 2 W, which matters when you're driving it from a PLC output or a bus-powered safety relay without an interposing relay.
This is a reversing contactor — two contactors mechanically interlocked so only one can close at a time, used to reverse a three-phase motor (conveyor, hoist, pump, fan). The 2 NC auxiliaries are on the reversing interlock side; you'd wire them into the opposite contactor's coil circuit to enforce the mechanical interlock electrically. The coil range (100-250 VAC/DC) covers common control voltages across 120 VAC and 230 VAC systems without needing a separate transformer tap.
