Why Choose the TE Connectivity RC55 U (x100) Horizontal Marker Card?
The TE Connectivity 1SNA230170R1000 is a pre-printed RC55 terminal block marker card designed for clear and consistent identification of terminals in industrial electrical panels, control cabinets and automation systems. Part of the TE Connectivity ENTRELEC RC55 marking range, it provides 100 identical “U” markings in a horizontal orientation for straightforward identification of compatible terminal assemblies.
Designed as a ready-to-use terminal marking accessory, the RC55 system helps panel builders, machine manufacturers and maintenance engineers maintain organised and easily identifiable electrical connections. The pre-printed format eliminates the need to produce individual labels manually, helping reduce installation time while maintaining consistent and legible identification throughout a terminal assembly.
The 1SNA230170R1000 features a white marker surface, 5 mm spacing and a UL 94V-2 flammability rating. Its horizontal format and repeated U marking make it particularly suitable for applications where multiple connection points require the same letter designation.

Clear Identification for Industrial Terminal Assemblies
Accurate terminal identification helps electrical engineers, panel builders and maintenance personnel trace circuits efficiently while reducing the risk of wiring and servicing errors. Pre-printed RC55 marker cards provide a standardised identification method that can be applied to compatible terminal assemblies without manually writing or printing individual labels.
With 100 repeated “U” markings and 5 mm spacing, the 1SNA230170R1000 is particularly useful where multiple terminals require the same letter designation. Its horizontal format provides neat and consistent identification for terminal assemblies used throughout industrial control, distribution and automation equipment.
Typical Applications
- Industrial electrical control panels.
- Automation and PLC control cabinets.
- Terminal block and terminal strip identification.
- Power distribution equipment.
- Machine building and OEM electrical systems.
