MS-8-140 is a marker strip component for the Series 140 barrier block system, specifically configured for 8-terminal applications. This marker strip is manufactured from Nema Grade XPC material with UL Rating 94V-O, providing durable identification and organization of terminal positions. The strip integrates with the Series 140 barrier block architecture, which features molded monoblock phenolic construction (UL Rated 94V-1) with brass eyelets and nickel plating for corrosion resistance. The marker strip operates within the same environmental specifications as the barrier block system, with an operating temperature range of -55°F to +300°F, and is RoHS compliant. This component is commonly used in industrial control panels, telecommunications equipment, and power distribution systems where clear terminal identification and protection against wire fraying are essential.
