Belden 6343PC 877, Multi Conductor Pro Audio Intercom 4C 18 AWG FEP
Description
Belden 6343PC 877 is a plenum-rated Security, Pro Audio & Intercom Cable for indoor plenum installations. It features a 4 pair design with 18 AWG stranded (7x26) BC - Bare Copper conductors and FEP - Fluorinated Ethylene Propylene insulation, with each pair individually Beldfoil® shielded. The cable includes a Flamarrest® jacket with ripcord and a drain wire to support shielding continuity. It is UL rated 300 V and meets NFPA 262 (UL 910) and FT6 requirements.
Belden 6343PC 877 Key Features
- Plenum fire rating supports use in indoor plenum environments.
- 4 pair construction with 18 AWG stranded (7x26) BC - Bare Copper conductors supports multi-pair signal wiring.
- FEP - Fluorinated Ethylene Propylene insulation helps maintain consistent pair insulation geometry.
- Individually Beldfoil® shielded pairs with 100% coverage and a 24 AWG (7x32) TC drainwire support shielding continuity.
- Flamarrest® jacket with ripcord supports easier pulls and jacket removal.
- UL voltage rating: 300 V.
- Flammability / reaction to fire: NFPA 262 (UL 910), FT6.
- Sequential footage marking every two ft supports measurement and pull tracking.
Belden 6343PC 877 Applications
- Use this cable for Security, Pro Audio & Intercom Cable installations that require multiple pairs for signal transmission.
- Route it indoors in plenum spaces where NFPA 262 (UL 910) and FT6 requirements apply.
- Choose it for installations that use individually shielded pairs to support noise rejection between circuits.
- It also fits pull-and-route jobs where a ripcord and sequential footage marking every two ft help with handling and measurement.
