WAGO

Wago, formally WAGO Kontakttechnik GmbH & Co. KG, is a German manufacturer of electrical interconnect and automation technology. The company is best known for its spring clamp electrical connectors, commonly referred to as Wago connectors, which enable tool-free termination of conductors and are widely used in electrical installations and control panels. In addition to lever-nut connectors, Wago produces PCB terminal blocks, modular terminal blocks, interface connectors, and other automation-related interconnection solutions.

History and development: Founded in 1951, Wago pioneered spring-loaded terminal block technology that replaced traditional screw clamps in many applications. This approach offered faster assembly, improved reliability, and greater flexibility in configuring electrical installations. Over time the company expanded internationally, building manufacturing and distribution networks to serve markets in Europe, Asia, and the Americas.

Technology and design: Wago connectors rely on a spring-loaded contact mechanism. When a conductor is inserted, the spring clamps down to secure the wire and establish a reliable electrical connection. The products are designed for a range of conductor sizes and insulation types, with features such as color-coding and modular compatibility to facilitate quick changes in circuits and layouts.

Applications: Wago components are used across residential, commercial, and industrial sectors. Common applications include building electrical installations, control panels in machinery, automation systems, and educational or research settings where quick and repeatable connections are advantageous.

Standards and presence: Wago products are manufactured to meet international electrical standards and are supported by a global sales and technical support network, providing certifications, documentation, and assistance to users and installers.
