The WAGO 280-601 is a 2-conductor pass-through terminal block from the series 280, finished in grey. It is designed for secure and fast connection of electrical conductors in industrial and building applications. The terminal block enables pass-through wiring, where the conductor is routed through the terminal, creating a direct connection between two conductors. The connection is made using CAGE CLAMP® technology, which provides a maintenance-free universal connection. The conductor is inserted into a cage spring, which automatically clamps it, ensuring a secure electrical connection. No pre-treatment of the conductor, such as crimping wire end ferrules, is required, which speeds up and simplifies installation.

Applications
This terminal block is suitable for use in industrial plants as well as in building electrical installations. It is commonly used in enclosures, distribution boxes, or control systems where reliable and fast conductor connections are required. Wiring can be done either as classic pass-through wiring or for potential distribution, allowing flexible use depending on the application.

Functions and Equipment in Detail
The 280-601 features side labeling slots, enabling labeling with WMB labels or other marking elements. This facilitates identification and maintenance of the installation. The terminal block is designed for mounting on standard support rails with dimensions 35 x 15 mm and 35 x 7.5 mm, ensuring universal use in various enclosure environments. Operation is performed using an actuation tool, which opens the cage spring to allow the conductor to be inserted.

Technology Explained Simply
The CAGE CLAMP® technology is based on a cage spring that automatically clamps the conductor as soon as it is inserted into the terminal. This technology allows connection of various conductor types — including bare, insulated, and wire end ferrule-equipped conductors — without additional pre-treatment. The terminal block is rated for conductor cross-sections from 0.08 mm² to 2.5 mm², with a maximum cross-section of 2.5 mm². The required stripping length is 8 to 9 mm, ensuring a precise and secure connection.

Compatibility and Accessories
The terminal block is compatible with various accessories that extend its functionality. These include group label holders such as the 209-141 or 209-142, used for labeling the terminal. For mounting on support rails, various steel support rails are available, such as the 210-114 or 210-506. Additionally, bridging combs such as the 280-482 or 280-492 can be used to electrically connect multiple terminals. Other compatible components include wire end ferrules such as the 216-102 or 216-202, which can be optionally used for specific applications.

Installation and Mounting
Mounting is done on a support rail with dimensions 35 x 15 mm or 35 x 7.5 mm. The terminal block is opened using an actuation tool, the conductor with a stripping length of 8 to 9 mm is inserted, and then secured again using the tool. The side labeling slots allow direct labeling with WMB labels, simplifying installation documentation.

Operational Advantages
The terminal block provides a fast and secure connection without requiring additional conductor pre-treatment. The CAGE CLAMP® technology ensures a maintenance-free and reliable connection that remains stable even under vibration or temperature fluctuations. The side labeling slots support clear identification, simplifying maintenance and fault diagnosis. Compatibility with various support rails and accessories increases installation flexibility.
