Colored: Standard colour: blue RAL 5010. By agreement, depending on the quantities, the motors can be painted in any colour or they can be delivered unpainted.

The motors comply with CE Directives: LVD and EMC. At request, the customer can receive a conformity declaration, and the label can be marked with CE logo.

Mechanical execution: protection degree IP 44, IP 54, IP 55.

Terminal box can be mounted upside , left-side and right-side of the housing.

The cable glands are with metric thread.

The rotor is with aluminium dye-cast squirrel-cage. The balancing is made with half key.

Electrical execution. Voltages and frequencies. Depending on order, the motors are made 50 Hz or 60 Hz net frequency and for voltages between 220V and 692V. By agreement between supplier and customer, the motors can be manufactured for lower voltages too.

Basic voltage is 230/ 400± 10% -50 Hz, the working conditions in the tolerance field being in accordance with point 12,3 and fig. 14 from IEC 34-1; that means that the rated parameters are guaranteed in their tolerance limits in accordance with IEC 34-1 for the dimensioning voltage, and at other voltage values it is ensured the main function of developing a couple corresponding to the rated power.

The motors insulation class is F. The motors in standard frame assignment have B class temperature rise. (temperature reserve of 25° C, motors can be utilized in surrounding temperatures up top 65°C instead of 40°C)
