What is inverter class H insulated copper enameled wire?
Inverter Operating Class H insulation is a specific type of insulation used for motors and transformers operating in inverter drive systems. Inverter drive systems often involve variable frequency drives (VFDs) or other power electronics, which can introduce higher voltage spikes, harmonic distortion, and rapid voltage changes.


Class H insulation is one of the highest temperature ratings defined by the National Electrical Manufacturers Association (NEMA) for enameled wire insulation. It can withstand higher temperatures than lower grades such as Class F and Class B. Class H insulation has a maximum allowable temperature rise of 180°C (356°F). This means that the insulation can withstand higher operating temperatures before degrading, making it suitable for demanding applications.

Copper enameled wire is a type of winding wire used in motors such as electric motors, transformers, inductors and other electromagnetic devices. It is made of copper, which is an excellent conductor of electricity, and coated with an insulating layer to prevent short circuits between the wire windings.

When you combine Class H insulation with copper enameled wire, you get a robust and efficient combination for high-performance motors and transformers used in inverter drive systems. This combination enables the equipment to cope with the increasing stresses, temperatures and electrical challenges posed by the rapidly changing voltages and frequencies in such applications.

In summary, Inverter H-rated insulated copper enameled wire is a high-quality electrical winding capable of withstanding high temperatures and is designed for use in motors and transformers operating in inverter drive systems with variable frequency drives.
