ANSHI 19 inch 200 Pairs JPX 202 Heigh Density 100 Pairs 128 Pairs Terminal Block
Summary:
Protection connection block is use in relay the following 2M to the local network or public communication telephone copper wire at the entrance, providing a range of over voltage, over current four sound and light alarm system. Can clearly distinguish visual alarm circuit to prevent external over-voltage over-current signal to the telephone exchange damage. Using for the internal and external wirings to the switch and accerss line to the user .
