Features
I Convenient kit for T1/E1 stations I Meets the T1 pulse mask as per ANSI T1.403 and the E1 mask per ITU G.703 I The protectors utilize PTC resistor technology for automatic resetting overcurrent protection and gas discharge tube technology for overvoltage protection Model 1830-A T1/E1 Protection Assembly, Rail Mounted Characteristics Bourns Model 1830-A T1/E1 Protection Assemblies provide secondary overvoltage protection for multiple T1 or E1 lines. DIN-3 Rail Mounted and able to accommodate future add-on modules, the assembly is designed to provide maximum surge protection caused from direct and induced lightning surges, power line disturbances and ground potential rises. Common installations of the 1830-A are power cabinets located in wireless base stations or other larger telecom service entrance terminals.
