Belden 6441FE 877 is a plenum-rated (CMP) security and sound cable built for reliable signal and control wiring in indoor spaces. It features 2 twisted pairs of 20 AWG stranded bare copper conductors with PVC - Polyvinyl Chloride insulation, along with an overall tape shield and drain wire to help reduce interference in noisy environments. The PVC - Polyvinyl Chloride outer jacket includes a ripcord for easier pulls and stripping, and the cable is rated 300 V with a max current of 3 Amps per Conductor at 25ºC.
