Description

The Legrand 037551 is a grey end cap for Viking 3 screw terminal blocks in the 1-entry/1-outlet configuration, compatible with the larger pitch sizes of 12mm and 15mm, corresponding to the 10mm² and 16mm²+ terminal blocks. Fitted at the ends of terminal rows, end caps enclose the open conductor entry side of the terminal block, preventing accidental contact with live conductors and providing a neat, finished appearance. They are a fundamental safety accessory for all professional terminal block installations.

The 037551 clips onto the terminal block without tools and is available in packs for cost-effective use across panel builds. It is specifically designed for the larger-pitch terminal blocks used for higher-current power distribution circuits within industrial and commercial control panels. Correct use of end caps is essential for achieving IEC touch-safe panel interiors and for presenting a professional, compliant terminal assembly.
