APPLICATION

• Overvoltage and transient voltage protection

DESCRIPTION

The varistors consist of a disc of low-ß ceramic material with

two solid copper leads (H20 types only) or copper clad steel

wire. The wires have a matte tin plating. They are coated

with a layer of ocher colored halogen- free epoxy, which

provides electrical, mechanical and climatic protection. The

encapsulation is resistant to all cleaning solvents in

accordance with IEC 60068-2-45.

MOUNTING

The varistors are suitable for processing on automatic

insertion, cutting and bending equipment.
