1sna230182r2100 – rc55 (100 x c) vert,

Why Choose the TE Connectivity RC55 1SNA230182R2100 Terminal Block Markers?

The TE Connectivity 1SNA230182R2100 is an RC55 pre-printed terminal block marker card designed for fast, clear and consistent identification of terminals in industrial electrical panels, switchgear and automation systems. Part of the TE Connectivity ENTRELEC RC55 marking range, this version contains 100 identical markers pre-printed with the letter C for vertical terminal block assemblies.

The RC55 marking system is designed for compatible ENTRELEC SNA and Solution series screw-clamp and spring-clamp terminal blocks, as well as Miniblocks. Using a pre-printed card eliminates the need to individually print repeated terminal identifiers, helping panel builders reduce marking time while maintaining a consistent and easily readable wiring identification system.

The 1SNA230182R2100 is manufactured from polyamide and features a white finish for clear identification. Designed for 5 mm terminal spacing, it has a UL 94 V2 flammability classification and a compact format suited to professional control-panel and machine-building applications.

Reliable Terminal Identification for Industrial Panels

Accurate terminal identification makes electrical panels easier to assemble, commission, inspect and maintain. Pre-printed RC55 marker cards provide a consistent identification method while reducing the preparation required when the same character needs to be applied across numerous connection points.

The RC55 1SNA230182R2100 is particularly useful where the letter C must be repeated across multiple vertically arranged terminals. Its 5 mm format and compatibility with appropriate SNA and Solution series terminals make it a practical marking accessory for organised industrial wiring installations.

Typical Applications

• Industrial electrical control panels.
• Terminal block and connection-point identification.
• PLC and automation cabinets.
• Switchgear and electrical distribution assemblies.
• Machine control and manufacturing equipment.
• OEM electrical panel building.
