It switches 38 A in AC-3 duty (≤440 V) — the standard category for starting and stopping squirrel-cage motors — and carries a 24 V AC 60 Hz coil with one normally open auxiliary contact.
The 38 A AC-3 rating governs motor switching up to that current; for resistive loads (AC-1) the contactor handles a higher current, but the AC-3 figure is the one that decides whether it matches your motor FLA. The 24 V AC coil draws from a control transformer — verify your control voltage is 24 V AC at 60 Hz, not 50 Hz or DC, because the coil impedance differs. The single NO auxiliary contact provides one feedback or interlock signal; if your circuit needs more, you'll add a side-mount auxiliary block.
