WAGO 249-117 Screwless End Stop for DIN Rail Terminal Blocks (Item No.: 249-117)

The WAGO 249-117 is a high-quality, screwless end stop designed to securely position and lock terminal blocks in place on standard DIN rails. This essential accessory ensures a stable and vibration-resistant terminal block assembly, preventing unwanted movement that could compromise electrical connections .

Key Features and Product Highlights

• Tool-Free, Snap-On Installation: Features a simple, tool-free design for fast and easy mounting. It snaps onto the DIN rail as quickly and effortlessly as a WAGO rail-mount terminal block .

• Secure Hold with Clamping Plates: Utilizes two small internal clamping plates that provide an excellent tight fit, keeping the end stop firmly in position even when the rails are mounted vertically .

• Universal DIN Rail Compatibility: Designed for use with all DIN-35 rails according to DIN EN 60715, specifically for rail types 35 x 7.5 mm and 35 x 15 mm .

• Versatile Marking Options: Features three marker slots compatible with all WAGO marker systems for rail-mount terminal blocks. It also includes a snap-in hole for WAGO adjustable height group marker carriers .

• Robust & Compact Design: Made with a gray housing from polyamide (PA66) with a flammability rating of V0 (UL94) . Its compact 10 mm width saves valuable space on the rail.
