It is rated for AC-3 duty at 6 A up to 440 V with a 24 V AC 50 Hz coil. That AC-3 rating means it is designed for starting and stopping squirrel-cage induction motors — the 6 A figure governs the motor full-load current it can switch, not the inrush.
A replacement for the AC-3 6 A / 440 V and 24 V AC 50 Hz coil combination may come from the current Easy TeSys or TeSys Deca range. Confirm pinout and mounting hole pattern against the panel layout.
