NKP-TEL-4C

The NKP-TEL-4C surge protector is designed to protect coaxial signal equipment against transients caused by lightning, electrostatic discharge and ground surges that can enter equipment from the signal lines. The NKP-TEL-4C features BNC connectors for camera, cable TV, cable network, and satellite antenna.

The systematic use of MOV, gas discharge tube and fast clamping diodes, provides a large discharge current capacity and low attenuation, ensuring reliable communication.

 *Installation Notes

1. Must disconnect power before installation, no hot-line operation is allowed, and better to under the guidance of professional electrician.
2. For best performance, mount protector in serial with the equipment it is protecting as close as possible, and better to install one protector at each end of the data line.
3. The ground wire on the product (if included) must be attached directly to the metal chassis of the equipment to be protected. The length of the grounded wire is not to exceed 11 inches.
4. No special maintenance is needed, however regular inspection is needed, especially during storm seasons.
