Advantage 1: SIMPLE – Easy-to-Use Design
Open the clamping unit, insert a conductor, release clamp – done! With the spring clamp, the conductor is secured by spring force, has a defined contact zone and can be easily released again by the spring mechanism. This technology is particularly user-friendly and easy to use. In addition, the universal connection, invented by WAGO in 1977 and now known as CAGE CLAMP®, allows all conductor types to be easily connected. It doesn't get any easier.
Advantage 2: FAST – Time and Cost Savings
WAGO's spring clamps are not only easy but also fast! They make connections in no time at all, which can save you significant time and labor costs. By automatically adjusting the spring force to the conductor size and type, it no longer needs to be prepared – thanks to the shorter wiring time, you reduce your effort for installing and maintaining systems and devices.
Advantage 3: SECURE – Optimal Conductor Retention
Safety is the top priority for the WAGO spring clamp: The clamping force adjusts automatically to the conductor so that the stripped conductor is pressed against the current bar in the defined contact zone – without damage. This technology ensures an optimal, secure grip. The advantage: Spring clamps cannot loosen on their own and guarantee a consistent, secure connection. In addition, they eliminate the risk of incorrect operation and can withstand overloads.
Advantage 4: OPERATOR-INDEPENDENT – A Good Connection Every Time
A good connection every time – regardless of the user? Spring pressure makes this possible because it automatically adjusts to the conductor cross-section. First, it ensures that the conductor is not clamped too tightly and is damaged. On the other hand, it prevents the conductor from being too loose and causing poor contact with high contact resistance. Operators no longer need to worry about potential interruptions. In addition, the clamping force compensates for any conductor deformation due to flow effects – for a constant connection!
Advantage 5: RELIABILITY – Constant Contact Quality
Spring pressure connection technology is highly reliable under all conceivable operating conditions and can be used safely in harsh environments – worldwide. Mechanical, electrical and climatic tests prove nothing shakes or loosens, even under extreme conditions. Interruptions in the electrical connection? Missing indication! WAGO’s spring-clamp terminal blocks pass difficult tests with flying colors and guarantee constant contact quality under the most demanding conditions, including those in shipping.
Advantage 6: DURABLE – Long-Term Contact Quality
Long live the spring pressure mechanism! After around 30 years of continuous use in railway technology, tests have shown that WAGO's terminal blocks have passed all tests and remain intact – with no trace of contact breaks, wear or corrosion. The clamping force of the spring is retained after being actuated multiple times and guarantees a permanent contact quality – over decades. WAGO's spring-clamp terminal blocks have proven themselves in all applications globally, making them ideal for use in systems with long lifecycles.
Advantage 7: CORROSION- AND TEMPERATURE-RESISTANT – High Resistance
Another special feature? The spring clamp is especially robust: It withstands aggressive atmospheres and extreme temperature changes from -40°C to +70°C and ensures long-term consistency of the contact resistance. Furthermore, corrosion does not affect the technology since the conductors are embedded in a tin layer, shielding them from corrosive gases. In addition, the spring clamp is designed for pollution degree 3 and can thus be safely used in rooms of industrial environments, unheated storage rooms and workshops.
Advantage 8: VIBRATION-PROOF – High Vibration and Shock Resistance
Our spring-clamp terminal block does not shock – even vibration tests, in which strong vibrations and shock peaks are simulated. In our stringent testing, the unit is positioned securely on a vibration system, shaken, rocked, and thus exposed to an ever stronger frequency band. The result: Due to the favorable mass distribution, the spring-clamp terminal block withstands even the highest vibrations of up to 2000 hertz and accelerations of up to 20g without contact interruptions, making it ready for any application!
Advantage 9: MAINTENANCE-FREE – Reduced Service Costs
With the maintenance-free spring-clamp terminal block from WAGO, you reduce your service costs and benefit from higher availability and reliability of systems and devices. In addition, WAGO's solutions help you avoid unnecessary downtime and reduce costs. For reliable use and maintenance-free contact – for decades.
Advantage 10: VERSATILE – Suitable for All Conductor Types and Applications
Spring-clamp terminal blocks are universal solutions that are flexible for all applications and suitable for all conductor types – whether solid, stranded or fine-stranded. The advantage is that you can connect all conductors without pretreatment. Ferrules can be used but are not required. You can benefit from the versatility of the spring clamp too!
