MARATHON/KULKA terminal block marking strips are essential accessories for organized and easily identifiable electrical circuits. These strips serve a dual purpose: providing insulation between terminal blocks and the chassis, and offering a printable surface for clear circuit identification. Available in materials like XP, XXXPFR, GME, and GEE, they cater to diverse application needs, including flame retardant requirements. The strips are compatible with a wide range of Marathon terminal blocks and can be customized with print styles for numbers, letters, or symbols. They are a crucial component for maintaining circuit integrity and simplifying troubleshooting in industrial and commercial settings.
