Engineered with WAGO’s trusted spring pressure connection technology, this connector ensures a secure electrical connection without the need for screws, crimping, or specialized tools. Whether you are a professional electrician, panel builder, or DIY enthusiast, the NC-221 connector delivers reliability, efficiency, and long-term performance in a wide range of electrical applications.

This 1 in 1 out wire connector is ideal for joining or extending conductors in control panels, lighting systems, junction boxes, automation equipment, and building wiring installations. Its compact footprint allows it to fit easily into tight spaces, making it especially suitable for modern electrical enclosures where space optimization is critical.

Reliable Spring Pressure Connection Technology

At the core of the WAGO NC-221 connector is advanced spring pressure connection technology, which automatically adjusts to the conductor and maintains consistent contact pressure over time. Unlike traditional screw terminals that can loosen due to vibration or thermal cycling, the WAGO spring mechanism ensures a stable, vibration-resistant connection throughout the life of the installation. This results in improved electrical safety, reduced maintenance, and minimized risk of connection failure.

Fast and Tool-Free Installation

The WAGO NC-221 connector is designed for quick and effortless installation. Simply insert the stripped conductor into the connector, and the internal spring securely clamps the wire in place. No screwdrivers, torque settings, or crimping tools are required. This significantly reduces installation time, especially when working on large projects or repetitive wiring tasks, helping professionals increase productivity and reduce labor costs.

Compact Design for Space-Saving Applications

With its slim and compact housing, the NC-221 wire connector is perfectly suited for installations where space is limited. It fits neatly inside standard junction boxes, distribution boards, and control panels without cluttering or obstructing other components. The compact design also improves airflow and organization within enclosures, contributing to a cleaner and more professional wiring layout.

Durable and Maintenance-Free Construction

Manufactured from high-quality, flame-retardant materials, the WAGO NC-221 connector is built to withstand demanding electrical environments. It offers excellent resistance to heat, mechanical stress, and aging. Once installed, the connection is maintenance-free, eliminating the need for periodic retightening or inspection commonly associated with screw-type connectors.
