The WAGO 280-833 is a 4-wire passage terminal block designed for use in industrial electrical installations. It enables secure and reliable connection of up to four conductors with a cross-section of 0.08 to 2.5 mm². The terminal block is finished in grey and features central labelling, allowing for clear identification of connections. It is designed for mounting on support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, ensuring universal use in various enclosures and distributions. The CAGE CLAMP® technology ensures a self-piercing, force-locked connection that requires no additional tools or screws, guaranteeing high contact quality.

Passage terminal block is the central term for this product, as it connects multiple conductors within a single connection component. The 4-wire function means that up to four individual conductors can be connected to one terminal block, with the connection achieved via CAGE CLAMP® technology. This technology is based on a self-piercing clamping mechanism that automatically adapts to the conductor cross-section and creates a stable electrical connection. The central labelling facilitates identification of individual terminals, especially in complex circuits, and helps prevent errors.

The terminal block is designed for use in enclosures and distributions where high mechanical stability and electrical reliability are required. It is particularly suitable for applications in automation technology, machine building, and building automation, where multiple conductors must be connected at a single point. The use on support rails of standard dimensions 35 x 15 mm and 35 x 7.5 mm is widely adopted in the electrical industry, allowing seamless integration into existing systems.

Support rail 35 x 15 mm and support rail 35 x 7.5 mm are the two standard dimensions on which the terminal block can be mounted. Thus, it is compatible with common rail profiles used in industry and electrical trade. The CAGE CLAMP® technology is a trademarked system by WAGO that enables a secure and durable connection without additional tools. The terminal block is designed for conductor cross-sections from 0.08 to 2.5 mm², allowing broad application for various conductor types, such as copper conductors.

To extend functionality, various accessories can be combined, such as insulation stops, bridging combs, end plates, or test adapters. These components support installation and maintenance by improving electrical insulation, enabling connections between multiple terminals, or facilitating testing of connections. Combination with steel support rails, such as 210-113 or 210-505, enables stable mounting in enclosures. The use of wire end ferrules, such as 216-101 or 216-103, can enhance connection security, especially with thin conductors.

The terminal block is finished in grey, providing a neutral and professional appearance. The colour does not indicate a specific function but is part of the standard design of the WAGO product line. Central labelling allows clear assignment of individual terminals, which is beneficial during commissioning and maintenance. The terminal block is mounted without additional tools, as CAGE CLAMP® technology enables simple and quick connections.

Operational advantages include high connection reliability, easy installation, and compatibility with standard support rails. The terminal block requires no additional tools for installation, reducing mounting time and error susceptibility. The use of CAGE CLAMP® ensures a durable, force-locked connection that remains stable even under vibrations and temperature fluctuations. Compatibility with various accessories extends functionality and allows application-specific adaptation.

The terminal block is designed for use in industrial environments where high mechanical and electrical load capacity is required. Typical use is in enclosures and distributions, where the terminal block is suitable for connecting conductors within an enclosure as well as for connection points on devices. Combination with test adapters, such as 209-170, allows easy testing of electrical connections without the need to disconnect conductors.
