Southwire Armorlite MC Cable 12/3, 100 ft – 600V Rated, Aluminum Armor, THHN/THWN Insulated

Overview

The Southwire Armorlite MC Cable is a reliable 12/3 metal-clad cable designed for commercial, industrial, institutional, and multi-residential power distribution. With solid copper THHN/THWN conductors, a green insulated grounding conductor, and a 600-volt rating, it provides a sturdy foundation for varied electrical layouts. The aluminum interlocking armor adds a balance of protection and flexibility, making it suitable for both exposed runs and installations inside trays or raceways.

Key features at a glance

• Premium copper conductors: Soft-drawn THHN/THWN wires rated for 90°C dry environments with a dedicated grounding conductor for safety and compliance.
• Durable aluminum armor: Interlocking armor protects the conductors while remaining flexible for routing through trays, ducts, and concealed spaces.
• Versatile applications: Ideal for branch, feeder, and service power distribution across commercial, industrial, institutional, and multi-residential buildings, supporting power, lighting, control, and signal circuits.
• Code-ready design: Approved for environmental air-handling spaces, places of assembly, theaters, and under raised floors for IT equipment, aligning with NEC considerations.
• Quality assurance: Conductors are cabled and bound with tape, and the product carries UL listing for trusted performance and safety standards.

Real-world use cases

In office complexes, schools, theaters, and data centers, Armorlite MC Cable can help organize robust power runs that need protection without excessive rigidity. Its 100 ft length provides ready-to-deploy options for standard room spans, while the 12/3 configuration supports multiple conductors within a single, shielded pathway. The combination of copper conductors and a green grounding conductor enhances system safety in environments with dense electrical layouts, lighting circuits, and IT infrastructure beneath raised floors.

Code, flame resistance, and safety highlights

• VW-1 flame test compatibility adds an extra layer of flame performance consideration for approved routes.
• UL-listed construction and compliance with relevant NEC references support NEC-ready installations in diverse spaces.

Why choose Armorlite for your installation?

Choosing Armorlite can offer a balance of protection and flexibility for both new builds and retrofit projects. The aluminum armor helps withstand mechanical demands in trays or concealed runs, while the copper conductors and insulation deliver solid electrical performance in dry environments up to 90°C. This cable is designed to align with common industry standards, helping project teams stay aligned with requirements for commercial and institutional facilities without overengineering the installation.
