1 Pair STB Connection Module or Drop Wire Module Overvoltage and Overcurrent Protection

1 Pair STB Connection module or Drop Wire module overvoltage and overcurrent protection
1 pair STB connection modules are designed for mounting on a standard DIN rail and can therefore be mounted in a variety of housings in whatever quantities are required. The small footprint (2 cm wide) ensures a compact product.
The Drop wire module be used for the connection of outdoor to indoor drop wire. It allows for circuit testing in both network directions. The box provides environmental protection.
