This standard applies to metal-oxide surge arresters (MOSA) designed to repeatedly limit the voltage surges on 48-62 Hz power circuits (> 1 kV) by passing surge discharge current and automatically limiting the flow of system power current. This standard applies to devices for separate mounting and to those supplied integrally with other equipment.
