Product Description
feature:
The protective junction block is used at the entrance of the relay below 2M to the copper wire of the local network or public communication telephone, providing a four-level sound and light alarm system for overvoltage and overcurrent within the range. It can clearly distinguish the visual alarm circuit and prevent external overvoltage and overcurrent signals from causing damage to the telephone exchange. Internal and external wiring for switches and user access wires.
feature
