Model C-303™ 5-Pin Gas Tube Protector Modules
Bourns® C-303™ 5-Pin Protector Modules provide overvoltage protection in the industry-standard 5-pin configuration for use in central
and remote office connector blocks as well as building entrance terminals.
The protector housing is made of self-extinguishing thermoplastic in black (standard service) or red (special service) colors. Modules
are available with either tin-alloy or gold-plated outside plant and central office pins. The ground pin is always tin-alloy plated. The pin
plating can be be matched with the receptacle plating of the connector block or building entrance terminal.
The protectors incorporate a fail-short design to ensure safe operation and protect people and equipment from prolonged electrical
surges.
