Why Choose the TE Connectivity 1SNA230243R1500 RC55 Terminal Block Markers?

The TE Connectivity 1SNA230243R1500 is an RC55 pre-printed terminal block marker card designed for clear and consistent identification of terminal connections in industrial electrical panels, control cabinets and automation systems. Part of the established Entrelec RC55 marking range, this version contains the number 3 repeated 100 times in a horizontal marking orientation.

The RC55 marking system provides ready-to-use numbers, letters and symbols for compatible terminal blocks, helping reduce the time required to produce individual identification labels. It is designed for marking compatible screw-clamp and spring-clamp terminal blocks and Miniblocks from the SNA and Solution series, supporting organised and readily traceable industrial wiring installations.

The 1SNA230243R1500 provides 100 identical “3” markers on a white polyamide card for 5 mm spacing. Each marker card weighs approximately 2.70 g and uses polyamide material with a V2 flammability classification, providing a practical identification accessory for professional panel building.

Clear Identification for Industrial Terminal Blocks

Terminal marking is an important part of professionally assembled electrical control systems. Clearly identified terminals allow engineers to match installed wiring with electrical schematics, simplify circuit tracing and reduce the time required for commissioning, inspection, troubleshooting and maintenance.

The RC55 range provides convenient pre-printed identification for compatible screw-clamp, spring-clamp and miniature terminal blocks. With 100 identical number “3” markings arranged for horizontal mounting and 5 mm terminal spacing, the 1SNA230243R1500 provides a practical solution wherever repeated numerical identification is required across industrial terminal assemblies.

Typical Applications

• Industrial electrical control panels.
• SNA and Solution series terminal block assemblies.
• Machine control cabinets.
• PLC and automation panels.
• Switchgear and electrical distribution equipment.
• Process control installations.
• Industrial wiring identification and maintenance.
