Overview

The ABB C221 Non-Insulated Locking Fork Terminal (SKU: C221) from ABB Installation Products delivers a robust and reliable solution for high-current industrial electrical connections. Engineered for wire sizes ranging from #12 to #10 AWG, this terminal ensures secure, low-resistance terminations in demanding environments where vibration, thermal cycling, and mechanical stress are common. Constructed from high-conductivity copper and finished with a corrosion-resistant tin plating, the C221 provides excellent electrical performance and long-term reliability, even in harsh conditions. The locking fork design incorporates internal barrel serrations to grip the wire securely, preventing slippage and maintaining consistent contact under load. This feature eliminates the need to remove the fastener during installation, significantly reducing assembly time and labor costs. The terminal’s #8 bolt hole accommodates standard mounting hardware, ensuring compatibility with a wide range of industrial panels, enclosures, and control systems. With a compact footprint measuring 0.85 inches in length and 0.37 inches in width, the C221 is ideal for applications with limited space, such as motor control centers, switchgear, and industrial machinery. Supplied in a bulk 500-piece pack, the C221 is optimized for high-volume installations, streamlining inventory management and reducing downtime. While this model is non-insulated, it meets industry standards for electrical connections and is designed for use in environments where insulation is not required or provided by adjacent components. Key applications include motor starters, transformers, power distribution panels, and industrial control systems where reliable, high-current terminations are critical. The C221’s durable construction and precise engineering make it a trusted choice for engineers and technicians seeking dependable performance in electrical termination systems.
