The HellermannTyton 561-01303 is a cable and wire marker that is used to easily identify and organize electrical wires, cables, and hoses. It features a label symbol of L1, L2, L3, N, and ground, which is easy to read and clearly communicates what each cable/wire is connected to. The marker is made of high-grade, UL-approved materials, making it durable and corrosion-resistant. Additionally, the marker is designed to easily attach to the surface of other components, meaning it can be placed pretty much anywhere to provide quick identification.
