7205 Series Surge Protection Assembly
Bourns® Model 7205 is a high quality surge protection device that is designed to prevent damage to equipment and personnel from
electrical transients up to rated limits. It incorporates Bourns® Gas Discharge Tube (GDT) surge protection for high surge-energy
handling with Insulation Displacement Connectors (IDCs) which simplify installation. Unstripped copper 22-26 AWG wire is inserted
and the connecter is closed – no tools required. The board-mounted components are enclosed in a UL Listed, weather-resistant
enclosure. A #10 stud is provided for connection to ground. The cover may be embossed with an optional custom logo.
