The product has a 600 volt class of insulation and is safe for operation on 600 volt drive systems. Because this product focuses on the 480 volt product, it will operate safely on a 600 volt line but the level of dV/dt will be slightly higher than on a 480 volt system. Performance tests resulted in distortion voltage peaks of around 1,200 volts instead of the 1,000 volt limits on a 480 volt system. This level is still considerably less than the typical peak distortion voltage of up to 2,100 volts found on 600 volt systems and should greatly assist in extending the life of the electric motor.
