Why Choose the TE Connectivity RC55 1SNA230035R2000 Terminal Block Marker Card?

The TE Connectivity RC55 1SNA230035R2000 is a pre-printed terminal block marker card designed for clear and consistent numerical identification of terminal connections in industrial electrical panels and automation systems. Part of the ENTRELEC RC55 marking range, this version provides the complete ascending numerical sequence 501 to 600, giving installers 100 consecutively numbered markers in a horizontal format.

RC55 pre-printed markers provide panel builders, machine builders and maintenance engineers with a convenient way to create uniform terminal identification without individually printing each number. Designed for marking compatible screw-clamp and spring-clamp terminal blocks and miniblocks from the SNA and Solution series, the continuous 501–600 sequence is particularly useful for larger installations where terminal numbers correspond with circuit diagrams, wiring schedules and equipment documentation.

Manufactured from white polyamide, the RC55 marking system uses 5 mm spacing and has a V2 flammability classification. The 1SNA230035R2000 contains 100 sequential markers and weighs approximately 2.7 g per card, providing a compact and practical solution for professional industrial terminal identification.

Sequential Identification for Industrial Terminal Assemblies

Sequential terminal numbering provides an important visual reference between physical electrical connections and their associated circuit documentation. Clearly numbered terminals simplify panel construction and commissioning while helping technicians trace individual connections efficiently during inspection, troubleshooting, modification and maintenance.

The RC55 1SNA230035R2000 supplies every number from 501 through 600 on one pre-printed marker card. This continuous sequence is particularly useful for larger terminal strips and installations extending into higher terminal numbers, while the horizontal coding direction and 5 mm spacing support orderly and consistent identification.

Typical Applications

• Industrial electrical control panels.
• Sequential terminal block and terminal strip numbering.
• Automation and machinery control cabinets.
• Power distribution assemblies.
• PLC and instrumentation panels.
• OEM machine and panel building.
• Process control installations.
• Electrical maintenance, expansion and retrofit projects.
