Connection terminals (wago terminals)

Connection terminals are the basic components of electrical systems, which are used to create safe and reliable connections between wires. They are used in both domestic electrical installations and industrial equipment to ensure a mechanically strong and electrically stable contact. Terminals allow multiple cables to be split, extended or connected without soldering or complicated working techniques.

There are several types of connection terminals in use. Quick terminals are suitable for quick and error-free connections, where the wires are secured using a spring system. They are particularly convenient in situations where it is necessary to save working time or where space is limited. Screw terminals provide a very strong and vibration-resistant contact, suitable for circuits with higher loads, electrical cabinets and industrial automation. Dead end terminals and end terminals are designed to properly terminate wires and protect the connection from oxidation and mechanical stress.

The use of connection terminals improves the safety and maintainability of the installation. A correctly selected terminal reduces the risk of overheating and ensures lower contact resistance, which is important for both low and high current loads. Terminals help make the installation more correct, clearer and more durable, while also providing the opportunity to easily change or expand the electrical system later.
