Industry Leading Coil Insulation System
GE pump motors are manufactured standard with a GEGARD2400 insulation system. This system exceeds NEMA MG1-31 (which is 3.1 times the nameplate voltage) for motors operating on inverters. This insulation system is comprised of class H materials. The combination of this and the varnish process provides a typical Corona Inception Voltage of 2400 volts peak with a rise time of 0.1 seconds.
