Overview

The ABB 3121-15 straight metal-clad cable fitting is engineered for secure termination and protection in electrical installations requiring metal-clad (MC) and armored cable (AC) systems. This fitting is constructed from malleable iron with a durable zinc plating, ensuring corrosion resistance and long-term durability in demanding industrial, commercial, and harsh environmental conditions. The interior features nylon insulation to safeguard cable conductors from abrasion and electrical interference, maintaining signal integrity and system reliability. Designed for trade size 2-1/2 inch applications, the 3121-15 fitting accommodates cables with a diameter range between 2.812 inches and 3.062 inches, providing flexibility for various armored or metal-clad cable types. The straight configuration simplifies cable routing in conduit systems, reducing installation complexity while ensuring a secure, vibration-resistant connection. The knockout size of 2-1/2 inch ensures compatibility with standard conduit systems, making it a versatile choice for new installations and retrofits. Key specifications include a trade size of 2-1/2 inch, knockout size of 2-1/2 inch, and a cable range of 2.812 to 3.062 inches. The malleable iron construction with zinc plating delivers robust performance in environments exposed to moisture, chemicals, or mechanical stress. The nylon insulation enhances electrical safety by preventing conductor damage during installation and operation. This fitting is optimized for use in metal-clad and armored cable applications where reliable termination and protection are critical.
