General information Insulation ABB uses class F insulation, which, with temperature rise B, is the most common requirement all industries today.   The use of Class F insulation with Class B temperature risegives ABB products a 25 °C safety margin. This can be used to increase the loading for limited periods, to operateat higher ambient temperatures or altitudes, or with greater voltage and frequency tolerances. It can also be used to extend insulation lifetime. For instance, a 10 K temperature reduction will extend the insulation lifetime.   Industry:   Thermal class 130 (B) –– Nominal...

The impact on temperature rise caused by voltage and frequency fluctuation is defined in IEC 60034-1. The standard divides the combinations into two zones, A and B. Zone A is the combination of voltage deviation of +/-5 % and frequency deviation of +/-2 %. Zone B is the combination of voltage deviation of +/-10 % and frequency deviation of +3/-5 %. This is illustrated in figure below. Motors are capable of supplying the rated torque in both zones A and B, but the temperature rise will be higher than at rated voltage and frequency. Motors can be run in zone B only for a short period of time.

The surface treatment categorization of ABB motors is based on the ISO 12944 standard. ISO 12994-5 divides paint system durability into three categories: low (L), medium (M), and high (H). Low durability corresponds to a lifetime of 2 - 5 years, medium to 5 - 15 years, and high durability to over 15 years. The durability range is not a guaranteed lifetime. Its purpose is to help the owner of the motor plan for appropriate maintenance intervals. More frequent maintenance may be required because of fading, chalking, contamination, wear and tear, or for other reasons. ABB’s standard surface...
