1sna229191r2500 – rc410 (100 x l) vert,

Why Choose the TE Connectivity RC410 1SNA229191R2500 Terminal Block Marker Card?

The TE Connectivity RC410 1SNA229191R2500 is a pre-printed terminal block marker card designed for clear and consistent identification of terminal connections in industrial electrical panels and automation systems. Part of the ENTRELEC RC410 marking range, this version contains 100 identical “L” markers specifically intended for vertical terminal block assemblies.

RC410 pre-printed markers provide panel builders, machine builders and maintenance engineers with a convenient way to create uniform terminal identification without individually printing each label. The repeated L marking makes the 1SNA229191R2500 particularly suitable where the same alphabetic identifier is required across multiple terminals, circuits or connection points.

Manufactured from durable white polyamide, the RC410 marker card has a V2 flammability classification and contains 100 pre-printed L markers. Its vertical configuration provides clear identification on compatible terminal block assemblies and supports organised wiring in control cabinets, machinery and industrial distribution equipment.

Clear Identification for Industrial Terminal Assemblies

Terminal block markers provide an essential visual reference for circuits and connection points within industrial electrical equipment. Clearly marked terminals make wiring easier to follow during panel assembly and commissioning while helping maintenance technicians locate individual connections quickly during inspection, troubleshooting and servicing.

The RC410 1SNA229191R2500 provides 100 repeated L identifiers on a single pre-printed card. Its vertical configuration makes it particularly suitable for compatible terminal assemblies where repeated alphabetic coding is required, helping maintain consistent identification throughout complex control and distribution systems.

Typical Applications

• Industrial electrical control panels.
• Terminal block and terminal strip identification.
• Automation and machinery control cabinets.
• Power distribution equipment.
• PLC and instrumentation panels.
• OEM machine and panel building.
• Process control installations.
• Electrical maintenance and retrofit projects.
