Features ■ ■ ■ Convenient kit for T1/E1 stations Meets the T1 pulse mask as per ANSI T1.403 and the E1 mask per ITU G.703 The protectors utilize PTC resistor technology for automatic resetting overcurrent protection and gas discharge tube technology for overvoltage protection ■ ■ ■ Both protectors can be on-site configured for either powered or unpowered spans Simplicity of DIN-3 rail mounting; the rail also serves as protector ground Vibration proof screw-type clamping connector interface Model 1830-A T1/E1 Protection Assembly, Rail Mounted 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.
