Belden 1312A 1SL, Multi Conductor Speaker Cable 4C 12 AWG FRPVC
Description
Belden 1312A 1SL is a 4-conductor, 12 AWG multi-conductor speaker cable with oxygen-free bare copper (high conductivity) conductors and a PVC - Polyvinyl Chloride jacket. It uses PE - Polyethylene insulation with color-coded conductors (Black, Red, White, Green) to simplify identification during termination. Electrical performance includes 1.6 Ohm/1000ft DCR, 22.3 pF/ft (73.2 pF/m) capacitance, and 0.15 μH/ft (0.49 μH/m) inductance. It is UL Voltage Rating: 300 V (CM, CL3) and includes sequential footage marking every two feet for easier pulls and cut-to-length accuracy.
Belden 1312A 1SL Key Features
- 4-conductor, 12 AWG multi-conductor speaker cable design for speaker wiring runs.
- Oxygen-free bare copper (high conductivity) conductors with stranding: 168x34.
- PE - Polyethylene insulation with color code: Black, Red, White, Green for easier conductor identification.
- PVC - Polyvinyl Chloride jacket for flexible handling.
- UL Voltage Rating: 300 V (CM, CL3).
- Sequential footage marking every two feet supports accurate measuring and cut-to-length pulls.
Belden 1312A 1SL Applications
- Use it as speaker cable for speaker runs that need a multi-conductor speaker wiring solution.
- Support direct burial installations when the cable route requires burial.
- Run indoor/outdoor home theater speaker wiring in home theater systems.
- Install it for in-wall speaker wiring where speakers are routed through wall cavities.
- Route it for outdoor speaker installations where the speaker wiring runs outdoors.
