Why Choose the TE Connectivity 1SNA199187R1400 D2.5/8.SFLT.ADO2 Fuse Terminal Block?
The TE Connectivity 1SNA199187R1400, type D2.5/8.SFLT.ADO2, is a grey ADO fuse terminal block with blown-fuse indication and test access from the Entrelec SNA ADO range. Designed for 5 × 20 mm and 5 × 25 mm cartridge fuses, it combines circuit protection, fuse-status indication and convenient testing within a compact DIN rail terminal format.
The terminal incorporates an orientable fuse holder and a 110–230 V AC neon blown-fuse indicator, helping maintenance personnel identify an open fuse more quickly. Its ADO connections are provided on both sides of the terminal, supporting conductor sizes from 1–2.5 mm² and providing a fast connection method for industrial control, automation and signal wiring.
With a rated current of 6.3 A, rated voltage of 500 V and rated cross-section of 2.5 mm², the 1SNA199187R1400 provides a compact protective connection for control circuits. The terminal is only 8 mm wide, provides IP20 protection at the main terminals and mounts on standard TH35 DIN rails, making it suitable for organised, high-density panel assemblies.

Fuse Protection with Visual Failure Indication and Test Access
The D2.5/8.SFLT.ADO2 combines three useful functions within one compact terminal position. A 5 × 20 mm or 5 × 25 mm cartridge fuse provides protection for the connected circuit, while the integrated neon indicator is designed to provide a visual indication when a fuse has opened in a compatible 110–230 V AC circuit. This can reduce the time required to locate a failed protective device during troubleshooting.
The orientable fuse holder allows convenient access to the cartridge fuse for inspection or replacement, while integrated test access supports commissioning and diagnostic measurements. ADO connections on both sides accommodate 1–2.5 mm² conductors, allowing the fuse terminal to integrate directly into Entrelec ADO wiring systems without requiring conventional screw-clamp conductor termination.
