POLYMER HOUSED ARRESTER-RISER TYPE MACLEAN POWER A current-responsive metal-oxide type device, with a simple and compact design for riserpole applications. Unit is described by its maximum continuous line-to-ground operating voltage (MCOV) because the most important application criterion is the maximum voltage which can be continuously applied. Clamping band, ground lead isolator, nut and wire clamp, and nut, wire clamp and protective cover included. 11-1/2" high. MCOV kV: 8.4, Ctn. Qty.: 1
