Belden 82777 877, Multi Conductor CMP Plenum 3 Pair 22 AWG FEP

Belden 82777 877 is a 3-pair, 22 AWG audio, control, and instrument cable for indoor plenum applications. It features 22 AWG stranded (7x30) TC - Tinned Copper conductors with FEP - Fluorinated Ethylene Propylene insulation and twisted pairs individually shielded with Beldfoil® (100% coverage) for noise rejection. A 22 AWG (19x34) TC drain wire supports grounding, and the PVC - Polyvinyl Chloride jacket provides protection. Key ratings and compliance include 300 V, 90°C, NFPA 262 (UL910), and NEC / UL Article 800, CMP.
