1sna230057r0600 – rc55 10x(161 a 170) vert,

Why Choose the TE Connectivity 1SNA230057R0600 RC55 Terminal Block Markers?

The TE Connectivity 1SNA230057R0600 is an RC55 pre-printed terminal block marker card designed for clear and consistent identification of terminals in industrial electrical panels, control cabinets and automation systems. Part of the established Entrelec RC55 marking range, this version carries the numbers 161 to 170 in a vertical orientation.

Accurate terminal identification helps panel builders, installers and maintenance engineers trace circuits efficiently during assembly, commissioning and servicing. The pre-printed RC55 format provides a convenient alternative to producing individual labels, helping maintain consistent and easily readable terminal numbering throughout an electrical installation.

The 1SNA230057R0600 provides the 161–170 numbering sequence repeated 10 times, making it particularly suitable for installations containing repeated terminal groups or circuits. Its white marker format provides high visibility when fitted to compatible terminal blocks and accessories.

Clear Terminal Identification for Industrial Panels

Terminal markers are an important part of professionally assembled control panels and electrical distribution systems. Clearly numbered connections allow engineers to match installed wiring with circuit diagrams and schematics, helping reduce errors during commissioning while making subsequent troubleshooting and maintenance more efficient.

The RC55 range provides a practical pre-printed identification solution for compatible terminal assemblies. With the 161–170 sequence repeated 10 times and arranged vertically, the 1SNA230057R0600 enables consistent identification of multiple terminal groups while reducing the time required for manual marking.

Typical Applications

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