MS-10-140 is a marker strip component for the Series 140 barrier block system, specifically configured for 10-terminal applications. It 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 architecture, which features molded monoblock phenolic insulation (UL Rated 94V-1), brass eyelets with nickel plating, and nickel-plated steel screws. This component operates reliably across a wide temperature range of -55°F to +300°F and is RoHS compliant. MS-10-140 is commonly used in industrial control panels, telecommunications equipment, and power distribution systems where clear terminal identification and organized wiring are essential for maintenance and troubleshooting.
