1sna230056r0500 – rc55 10x(151 a 160) vert,

Why Choose the TE Connectivity 1SNA230056R0500 RC55 Terminal Block Markers?

The TE Connectivity 1SNA230056R0500 is an RC55 pre-printed terminal block marker card designed to provide clear, durable identification of terminal connections in industrial electrical panels and automation systems. Part of the established Entrelec RC55 marking system, this version is pre-printed with the numbers 151 to 160 in a vertical orientation.

RC55 markers provide an organised method of identifying terminal blocks, helping installers, maintenance engineers and panel builders trace electrical circuits quickly and accurately. The pre-printed format eliminates the need to produce individual identification labels during panel assembly, helping reduce installation time and maintain consistent marking throughout an enclosure.

The 1SNA230056R0500 is supplied as a white polyamide marker card containing the sequence 151–160 repeated 10 times. It is designed for compatible screw-clamp, spring-clamp and miniature terminal blocks within the SNA and Solution terminal block families.

Clear Identification for Industrial Terminal Blocks

Reliable terminal identification is essential in control panels, switchgear and automation equipment. Clearly marked terminals make wiring easier to verify during installation and help maintenance engineers locate circuits efficiently when testing, servicing or modifying electrical systems.

The RC55 marking range provides pre-printed identification for compatible Entrelec terminal blocks. With its vertical 151–160 numbering sequence repeated across the card, the 1SNA230056R0500 provides a convenient solution for consistently identifying groups of terminals without individually printing each marker.

Typical Applications

• Industrial electrical control panels.
• Terminal block assemblies.
• Machine control cabinets.
• PLC and automation panels.
• Switchgear and distribution equipment.
• Industrial wiring identification and maintenance.
