MS-16-140 is a marker strip component for the Series 140 barrier block system, specifically configured for 16-terminal applications. This marker strip is constructed from Nema Grade XPC material with UL Rating 94V-O, providing durable identification and organization of terminal positions. The marker strip integrates with the Series 140 barrier block system, which features molded monoblock phenolic insulation (UL Rated 94V-1), brass eyelets with nickel plating, and nickel-plated steel screws. The complete barrier block system supports electrical ratings of 250 VAC RMS maximum with 15 Amps maximum current per terminal, accommodating wire sizes up to #16 AWG. MS-16-140 is commonly used in industrial control panels, telecommunications equipment, and power distribution systems where clear terminal identification and protection against wire fraying are essential.
