7205 Series Standard-Size Surge Protection Assembly
Bourns® standard-size 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.
