Features ■ Front-facing confi guration - easy access to protector modules, jumper fi eld and test fi eld ■ Increased density - confi guration increases pair density by 25 percent when compared to traditional 303-type connector blocks ■ Industry-standard design - Accepts all standard 303-type protector modules and testing equipment ■ Integral fanning strip helps maintain neat and orderly wiring Model C(G)-310 100-Pair Connector Bourns® C(G)-310 Connector is intended for applications where protector pair density and front-facing protector modules, test fi eld and jumper fi eld are important. It is ideal for “protector only” frames where the jumpering between the switching equipment and the connector is done on separate, intermediate distributing frames. This 362 mm high (14.25 inch) connector maintains the basic features of the 303 connector while increasing the protected pair density by 25 percent compared to the C(G)-303. The C(G)-310 connector consists of a one-piece, fl ame retardant, molded plastic panel fastened to a rugged metal mounting bar to provide sturdiness. The C(G)-310 connector may be used on central offi ce mainframes with 203 mm (8 inch) between verticals. The C(G)-310 connector accepts the full line of industry standard 303-type, 5-pin protector modules including Bourns® hybrid, solid-state and gas tube modules.
