The Cooper Power AZL19C509R MOV Arrester is a metal-oxide varistor surge protection device designed to guard electrical equipment from transient overvoltages. It provides a 9 kV rated voltage and a 7.65 kV MCOV (maximum continuous operating voltage), indicating the voltage range it can continuously handle while clamping spikes. As part of the AZL MOV arrester family, it is intended for surge protection in electrical distribution equipment and other circuits where fast response to transient voltages is required.
