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.
