Hello only the first one happened because the other one doesn't look good step to explain each item 1) Rated current 25A in alternating 2) 1000V insulation voltage (1kV) 3) maximum peak voltage 8 kV 4) nominal power in kW according to supply voltage 5) idem 4 6) nominal power in HP according to supply voltage 7) rated current in continuous 8) maximum working temperature 9) 3 phases alternating current 10) AC3 contactor classification according to its degree of use, in this case it indicates that it is suitable for repeated drives per minute in inductive loads the coil voltage is surely contained in terminals A1 and A2
