Why Choose the TE Connectivity RC55 1SNA230038R0300 Marker Card?

The TE Connectivity 1SNA230038R0300 is a pre-printed RC55 terminal block marker card designed for clear and sequential identification of electrical terminals in control panels, switchgear and industrial automation systems. Part of the established TE Connectivity ENTRELEC RC55 marking range, this version provides an ascending sequence of 801 to 900 arranged for horizontal terminal identification.

Clear terminal identification helps simplify panel assembly, commissioning, troubleshooting and maintenance by allowing individual connection points to be recognised quickly. The RC55 marking system provides a practical and professional identification solution for compatible terminal blocks, helping panel builders and electrical engineers create organised, traceable and easily serviceable terminal assemblies.

The 1SNA230038R0300 marker card is supplied in white and contains 100 sequentially numbered markers from 801 through 900. Its horizontal marking orientation makes it suitable for installations where terminal numbers need to be read horizontally, providing a ready-to-use identification solution without requiring individual marker printing.

Reliable Sequential Identification for Electrical Terminal Blocks

Terminal block markers provide an immediate visual reference for individual connection points within electrical panels and automation equipment. Sequential numbering makes it easier for engineers to match terminals with wiring diagrams, trace circuits, verify connections and carry out maintenance while reducing the possibility of confusion between neighbouring terminals.

The RC55 marking system provides a practical solution for professional electrical installations where clear and consistent identification is important. With numbers 801 through 900 factory printed in ascending order and arranged horizontally, the 1SNA230038R0300 provides a ready-to-use solution for sequentially identifying compatible terminal assemblies without the need for on-site marker printing.

Typical Applications

• Electrical control panel terminal identification.
• Industrial switchgear and distribution equipment.
• PLC and automation control cabinets.
• Machine building and OEM electrical assemblies.
• Process control and instrumentation panels.
• Maintenance and refurbishment of compatible ENTRELEC terminal installations.
