It carries a 40 A rating in AC-3 and AC-3e utilisation categories at ≤440 V, with a 440 V AC 60 Hz coil. The part is now obsolete per the manufacturer.
The 40 A AC-3 rating governs switching of squirrel-cage motors during starting and running — that is the figure to match against your motor FLA. AC-3e is a variant for energy-efficient motors with higher inrush. The 440 V AC coil means the control voltage must match; verify your control transformer output before wiring. The contactor carries approvals to EN/IEC 60947-4-1 (the main standard for contactors and motor-starters) and GB/T equivalents, so it fits installations that require CCC-level compliance.
Dimensions are 75 mm wide, 127 mm high, 114 mm deep — standard footprint for the Easy TeSys frame. IP2X finger protection on the contactor body; the TH protective treatment (pollution degree 3) means it handles humid, non-condensing environments per IEC 60068-2-30.
