The WAGO 249-116 is a screwless end clamp with a width of 6 mm, specifically designed for mounting on support rails in formats 35 x 15 mm and 35 x 7.5 mm. It serves as a termination component in enclosures and electrical distributions, used to finish the ends of terminal blocks and ensure a neat, secure conclusion to the installation. The end clamp is finished in grey, thus matching the standard colour scheme of WAGO products, which is widely used in industrial electrical engineering.

Applications

The end clamp is used in industrial electrical installations where a clean and secure termination solution for terminal blocks is required. It is particularly suitable for enclosures, distribution boxes, and control systems where support rails conform to DIN 46227-1 (35 mm width) are used. Applications include automation systems, machine building, and building automation, where structured and clear wiring is essential.

Functions and Features in Detail

The screwless mounting allows for quick, tool-free attachment to the support rail. The clamp is simply snapped onto the rail and secured by an integrated locking mechanism. This reduces installation time and minimizes the risk of errors during installation. The 6 mm width corresponds to the standard for individual terminals, enabling compact arrangement in confined mounting areas. The grey finish is neutral and blends in with typical enclosure colour schemes.

Technology Explained Simply

The end clamp is made from a robust plastic material designed for industrial environments. The screwless fastening is achieved via an elastic spring mechanism that securely holds the clamp on the support rail. The design ensures a stable connection without requiring additional fastening elements. The clamp is not intended for electrical conductor connections, but serves purely as a mechanical termination.

Compatibility and Accessories

The WAGO 249-116 is compatible with support rails in formats 35 x 15 mm and 35 x 7.5 mm, which are standard in industrial electrical engineering. Compatible accessories include various labelling systems such as the WMB multi-labelling system (e.g. 793-5501/000-002, 793-5501/000-017) and mini-WSB quick-labelling systems (e.g. 248-501/000-007, 248-501/000-006). These systems allow for clear identification of terminal blocks. Additionally, carrier pass-through elements (e.g. 709-118) and height-adjustable group label carriers (e.g. 249-119, 249-120) are available to support labelling and structuring of enclosures.

Mounting and Installation

Installation is tool-free: the end clamp is simply snapped onto the support rail and secured by the integrated locking mechanism. No additional fasteners or tools are required. The installation is quick and can be performed even in confined spaces. The clamp is not intended for electrical conductor connections, but serves exclusively as a mechanical termination.

Operational Advantages

The screwless design reduces mounting time and minimizes the risk of installation errors. The robust construction ensures long service life and reliability in industrial applications. Compatibility with standard support rails and the availability of labelling systems facilitate integration into existing enclosure configurations. The grey finish supports a uniform visual appearance of enclosures.

The end clamp is not designed for electrical conductor connections, but serves purely as a mechanical termination. Installation is tool-free and therefore quick and easy. Use is limited to the specified support rail formats.
