Sample application: Protection against a high-energy surge in industrial devices
Block varistors and strap varistors are high-energy type products used for power supplies of industrial devices and communication devices, power switchboards at power plants and power substations, railway signal systems, and others, and their advantage is an extremely high surge current capability. A block varistor is contained in a case and has screw terminals, and a strap varistor has strap (flat plate) terminals with holes that are fixed with screws (or soldered). A surge arrester for AC power line protection is also used.
