Its headline rating is 12 A in AC-3 utilisation category at ≤440 V, meaning it switches three-phase induction motors drawing up to that current — typical for a 5.5 kW motor at 380–415 V or 4 kW at 480 V. The coil is 110 V AC and includes a built-in bidirectional peak limiting diode suppressor, so you don't need an external snubber across the coil for most PLC or relay outputs. The contactor carries three normally-open power poles and one normally-open auxiliary contact. It's rated for AC-1 (resistive), AC-3 (squirrel-cage motor starting/running), and AC-4 (plugging/inching) duty, so it covers both standard motor starts and more demanding reversing or jogging applications.
Wire the power circuit through the three NO poles, connect the 110 V AC coil to the A1/A2 terminals, and use the single NO auxiliary for feedback to a PLC input or for electrical interlocking. The built-in coil suppression handles the inductive kick — no external diode or RC snubber needed across the coil.
