Rated AC-3 at 12 A up to 440 V, it handles reversing motor loads like conveyors, hoists, or pump direction changes. The 115 V AC coil and one NC auxiliary contact are built in; the contactor snaps onto a DIN rail inside a control panel (IP20 finger-safe per VDE 0106).
The AC-3 rating of 12 A at <= 440 V is the motor-switching current — this is the number that decides whether the contactor can start and stop a given induction motor under load. AC-4 covers plugging and inching duty (higher wear). The 115 V AC coil means the control transformer or PLC output must supply 115 VAC; verify the control voltage matches your panel design. The 1 NC auxiliary gives one normally-closed feedback contact for status or interlock. Dimensions are 90 mm wide, 58 mm high, 57 mm deep — compact enough for a crowded DIN-rail row. Ambient operating range is -25 to 50 °C, storage -50 to 80 °C. Altitude derating starts above 2000 m.
