Nameplates

• Each arrester is identified with an arrester nameplate attached to its bottom casting. • Arrester nameplates display the MCOV (Uc), duty cycle rating (Ur) pressure relief current, serial and catalog numbers as required by IEEE or IEC standards. • On multiple-unit stacks, the plate is attached to the bottom unit. It features all of the same information as well as the stacking sequence. • Multiple-unit arresters must be stacked in the order listed on the base nameplate. The stacking sequence is also listed on the arrester crates for easy reference. • Additionally, multiple-unit stacks feature a unit nameplate on the upper casting of each unit. This identifies the serial number of the specific unit.
