55275021 Armored Cable, 12/3 Thhn Copper, Steel Jacket, 25 Ft.

Southwire's 12/3 armored cable is a heavy-duty electrical solution designed for professional and residential installations requiring mechanical protection and reliable power distribution. The cable features three 12 AWG soft-drawn copper conductors with THHN/THWN insulation, wrapped individually with moisture-resistant, flame-retardant paper and enclosed in interlocking steel armor. This construction shields the conductors from physical damage while maintaining excellent conductivity for consistent voltage performance.

This armored cable is ideal for branch, feeder, and service power distribution in commercial, industrial, institutional, and multi-residential buildings. It handles power, lighting, control, and signal circuits in both concealed and exposed installations, including cable tray, approved raceways, environmental air-handling spaces, and under raised floors for information technology equipment. The steel jacket provides superior protection against impact, abrasion, cuts, and crushing forces—critical for installations in harsh environments or areas where rodent damage is a concern.

Features and Benefits

• Interlocking Steel Armor: Offers exceptional mechanical protection against physical stress, impact, and abrasion, extending cable lifespan and reducing installation risk.
• Soft-Drawn Copper Conductors: Ensures excellent conductivity and low-resistance power transmission for efficient, code-compliant electrical systems.
• 16 AWG Aluminum Bond Wire: Runs longitudinally inside the armor in intimate contact for reliable grounding and bonding that meets NEC requirements.
• Moisture-Resistant Paper Covering: Protects individual conductors from environmental moisture and flame hazards during installation and operation.
• 25-Foot Length: Provides a practical coil size for residential and commercial electrical projects.
