It switches 6 A in AC-3 duty (≤440 V) and carries a 440 V AC 60 Hz coil with one normally-closed auxiliary contact. The 1.5 ms non-overlap time between NC and NO contacts is guaranteed on both energisation and de-energisation, which matters for interlocking circuits where you need to avoid a momentary bridge.

This part is listed as obsolete. There is no official successor order code, so any replacement will need a parametric cross-reference.
AC-3e is the same duty with extended electrical life for standard induction motors.
Compliant with EN/IEC 60947-1, -4-1, and -5-1, plus GB/T 14048.1.4, and.5. Fire resistance tested to 850 °C per IEC 60695-2-1. Protective treatment TH (pollution degree 3) per IEC 60068-2-30 means it handles damp heat in industrial environments.
