MYE30-471 380J Metal Oxide Varistor Surge Suppressor Varistor with Screw Terminals M5

Heavy Duty Disk Metal Oxide Varistor MYE30-471 B32K300 With Screw Terminals M4 M5

Description Of The Heavy Duty Disk Metal Oxide Varistor MYE30-471

Block varistors are disk shaped varistor elements that are potted in a plastic housing and feature screw terminals on top. Block varistors can be screw fixed and used as stand-alone devices. Both the housing and potting are made of flame-retardant materials.Housing varistor; The inside varistor diameter is 32mm round shape.C type terminal, equal to EPCOS High E B32K series,5. Peak Current: 30000A, MYE varistors are designed for heavy industrial electric products of extremely high demand on surge withstanding capacity, as well as poor working environments.

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.
