Part identity and key ratings
It carries a 9 A rating in AC-3 and AC-3e utilisation categories at ≤440 V, with a 110 V AC 50/60 Hz coil and one normally-open auxiliary contact built in.
The AC-3e rating extends that to energy-efficient IE3/IE4 motors with slightly different switching characteristics. For purely resistive loads (AC-1), the contactor can carry a higher current, but the 9 A AC-3 figure is the one that decides fit for most motor-control BOM lines.
Fire resistance tested to 850 °C per IEC 60695-2-1. Protective treatment TH (pollution degree 3) per IEC 60068-2-30 means it's suitable for environments with high humidity and some condensation — typical for industrial control panels in non-conditioned spaces.
