Maintenance-Free Spring Pressure Connection Technology

Using safe and maintenance-free connection technology can considerably lower investment costs over a system’s entire lifecycle.

Electrical conductors and the quality of their connections determine machine and system uptime – regardless of the complexity of the system’s automation structure or its functions. Electrical connection technology must elevate one feature above all the others: reliability. And it must maintain reliability under all conditions and over the complete lifecycle of the system.

Your Benefits with WAGO:

CAGE CLAMP® provides safe and maintenance-free connections – and has proven itself for decades.
The spring pressure connection technology is well-equipped for demanding environments.
Installation and wiring work is fast and needs no special instructions.

The Right Connection Technology Cuts Costs

Mechanical engineers and system designers must offer their clients solutions that guarantee a high level of system uptime and reduce the total cost of ownership over the system's entire lifecycle. This places a tremendous amount of pressure on those providing systems to the chemical and process industries, as well as shipbuilding. The components used here must brave some of the roughest environmental conditions and must perform flawlessly, until they are replaced during scheduled maintenance. This is why the importance of the connection technology for all types of electrical connections should not underestimated in mechanical and systems engineering. Ultimately, using safe and maintenance-free connection technology can provide significant levels of investment protection during a system’s lifecycle. From the view of a system engineer or operator, usability should not come at the cost of safe and maintenance-free electrical connections. From both aspects – the connection quality and usability – the type of connection technology is the deciding factor.

Easy Spring Clamp Connections

Allowances must be made for copper, which has unique flowing characteristics that can be impaired if a screw connection is too tight. Over time, screws loosen, contact resistance increases and the connection becomes impaired. Shocks, vibrations and temperature fluctuations can impair the contact quality of a screw connection. Shocks and vibrations occur commonly in marine applications; temperature fluctuation demands of −40°C to +70°C can occur in control cabinets that are installed in open-air sites located in areas with extreme climates. Conductor specifications, such as stripped copper conductors, or conductors with lamellar or woven structures, also influence contact quality. For instance, conductors formed from a mesh of thin, individual wires are quickly destroyed by screw connections.

Reliable under All Conditions

In contrast to screw connections, WAGO's spring pressure connection technology provides safe and maintenance-free connections for electrical conductors – and has proven itself for decades. They first demonstrate their advantages during installation and later during use: correctly connected from the start, the spring clamp connections endure even the harshest circumstances. Because contact pressure that embeds the conductor into the current bar is determined by the spring, basically making it “pre-programmed” to always function optimally. The quality of the clamping point remains consistent, despite shocks and vibrations, because the spring automatically compensates for these to maintain connection integrity.
