Epoxy Coated Series

The LE types are heavy-duty metal oxide varistors designed mainly for industrial applications. They are larger diameter versions of the conventional metal oxide varistor disc components. The LE Series has rigid terminals to handle high currents and energies. Either straight or formed terminals are available. The latter facilitates mounting onto printed circuit boards. The LE Series offers excellent surge protection for use in industrial and consumer electrical equipment, power distribution, control equipment, security/fire alarm systems, railroad equipment, switchboards, computers, telecommunications, power supplies and motor controls. The advantages of the LE version are: simple design, rigid terminals for secure mounting, high performance on limited space.
