1sna230054r0300 – rc55 10x(131 a 140) vert,

Why Choose the TE Connectivity RC55 1SNA230054R0300 Marker Card?

The TE Connectivity 1SNA230054R0300 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 is pre-printed with the numbers 131 to 140 repeated 10 times and arranged for vertical terminal identification.

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

The 1SNA230054R0300 marker card is supplied in white and provides 100 pre-printed markers in total, comprising the sequence 131–140 repeated 10 times. Its vertical marking orientation makes it suitable for installations where terminal identification needs to be read vertically, providing a convenient factory-printed alternative to individually produced terminal labels.

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 the numbers 131 through 140 factory printed 10 times and arranged vertically, the 1SNA230054R0300 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.
