NTE524V15 MOV 160V RMS Dia=23mm 80 Joules Itm=6500A Clamping Voltage=410V
 
The NTE Metal Oxide Varistors feature a barrier layer that gives the user fast response time. These devices have a high transient current handling capability when high voltage is applied. Static resistance is, however, very high under low voltage conditions, permitting low standby drain currents.
