10 Advantages of CAGE CLAMP®

As the inventor of spring-clamp connection technology, WAGO has provided simple, fast and maintenance-free connection solutions since 1951. The principle is straightforward: spring force secures conductors without screws. Today, this technology is a global standard that helps electrical professionals handle even complex wiring tasks. Discover the everyday advantages of spring-clamp connection technology.

Advantage 1: SIMPLE - Easy-to-Use Design

Open the clamping unit, insert a conductor and release the clamp. That's it! Spring force holds the conductor securely in a defined contact zone, and the spring mechanism makes it easy to release. This user-friendly technology simplifies wiring. WAGO's universal connection technology, introduced in 1977 and now known as CAGE CLAMP®, accommodates solid, stranded and fine-stranded conductors. It couldn't be easier.

Advantage 2: FAST - Time and Cost Savings

WAGO's spring-clamp connections are quick and easy to install. They can significantly reduce wiring time and labour costs. The spring force automatically adapts to the conductor's size and type, eliminating the need to adjust the clamping force manually. Shorter wiring times reduce the work involved in installing and maintaining systems and devices.

Advantage 3: SECURE - Optimal Conductor Retention

Safety is a top priority. The clamping force automatically adapts to the conductor, pressing the stripped conductor against the current bar within a defined contact zone without damaging it. This provides a secure, reliable hold. Spring-clamp connections resist loosening, helping maintain a consistent connection. They also help reduce the risk of incorrect installation and are designed to withstand overload conditions.

Advantage 4: OPERATOR-INDEPENDENT - A Reliable Connection Every Time

Spring pressure helps deliver a consistent connection regardless of who performs the installation. The clamping force automatically adapts to the conductor cross-section, preventing both excessive pressure that could damage the conductor cross-section, preventing both excessive pressure that could damage the conductor and insufficient pressure that could lead to poor contact and increased contact resistance. It also compensates for conductor deformation caused by material flow, maintaining a stable connection.

Advantage 5: RELIABLE - Consistent Contact Quality

Spring-pressure connection technology provides reliable performance across a wide range of operating conditions, including harsh environments. Mechanical, electrical and climatic testing demonstrates that connections remain secure even under extreme conditions. WAGO's spring-clamp terminal blocks undergo demanding tests to verify consistent contact quality, including in marine environments.

Advantage 6: DURABLE - Long-Term Contact Quality

Tests following approximately 30 years of continuous service in railway applications have shown that WAGO terminal blocks remained intact, with no evidence of contact interruptions, wear or corrosion. The spring retains its clamping force even after repeated actuation, helping maintain contact quality for decades. Proven in applications around the world, these terminal blocks are well suited to systems with long service lives.

Advantage 7: CORROSION AND TEMPERATURE-RESISTANT - Dependable Performance in Harsh Conditions

Spring-clamp technology is built to withstand harsh atmospheres and temperature changes from −40°C to +70°C while maintaining stable contact resistance. Conductors are embedded in a layer of tin that helps protect the contact area from corrosive gases. Designed for pollution degree 3, the technology is suitable for industrial spaces, unheated storage areas and workshops.

Advantage 8: VIBRATION-RESISTANT - High Shock and Vibration Resistance

WAGO's spring-clamp terminal blocks are designed to withstand vibration and shock. During rigorous testing, terminal blocks are mounted on a vibration system and subjected to increasing frequencies and simulated shocks. Thanks to their favourable mass distribution, they withstand vibrations up to 2,000 Hz and accelerations up to 20 g without interrupting electrical contact.
