The ABB CL-100Y is a 22.5 mm compact pilot light designed for a variety of industrial control panels. This yellow pilot light stands out for its versatility, meeting multiple NEMA ratings including 1, 3R, 4, 4X, 12, and 13, which means it’s built to handle different environmental conditions without breaking a sweat. One great convenience is that it doesn’t need extra contact blocks or holders, simplifying installation.
