1sna230049r1600 – rc55 10x(81 a 90) vert,

Why Choose the TE Connectivity RC55 1SNA230049R1600 Terminal Block Marker Card?

The TE Connectivity RC55 1SNA230049R1600 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 numbers 81 to 90 repeated 10 times, creating a total of 100 pre-printed markers in a vertical format.

RC55 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 81–90 sequence is particularly useful where several terminal groups require the same numerical identification pattern, helping maintain a clear relationship between physical terminals, wiring diagrams and circuit documentation.

Manufactured from durable white polyamide, the RC55 marking system uses 5 mm spacing and has a UL 94 V-2 flammability classification. The 1SNA230049R1600 is configured for vertical identification and provides 100 ready-to-use numerical markers for professional electrical panel construction, commissioning and maintenance.

Efficient Numerical Identification for Terminal Assemblies

Clear terminal identification is essential for organised electrical panel construction, commissioning and maintenance. Numbered markers allow installers and technicians to associate individual terminals with wiring diagrams and circuit documentation, helping connections to be located efficiently during installation, inspection, troubleshooting and servicing.

The RC55 1SNA230049R1600 provides the ascending sequence from 81 through 90 repeated 10 times on one pre-printed card. This arrangement is particularly convenient when several terminal groups require the same numbering pattern, while the vertical coding direction and 5 mm spacing support clear and consistent identification across compatible terminal assemblies.

Typical Applications

• Industrial electrical control panels.
• 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 and retrofit projects.
