Why Choose the TE Connectivity 1SNA230131R2500 RC55 Marker Card?

The TE Connectivity 1SNA230131R2500 is a pre-printed RC55 terminal block marker card designed for clear and consistent identification of electrical connections in control panels, distribution equipment and industrial installations. Part of the ENTRELEC terminal block marking accessory range, this marker card provides the pre-printed sequence L1-L2-L3-N-PE for straightforward identification of three-phase, neutral and protective earth connections.

Designed specifically for professional terminal identification, the RC55 marker card uses a horizontal marking orientation and a white background to provide clear visual recognition within densely populated terminal assemblies. The pre-printed format eliminates the need to individually print or hand-mark identification labels during panel assembly and maintenance.

The 1SNA230131R2500 provides the L1-L2-L3-N-PE sequence repeated 20 times and features a 5 mm marking pitch. Its durable construction and UL 94V-2 flammability rating make it suitable for identification duties within industrial electrical equipment where organised, dependable terminal marking is required.

Reliable Terminal Identification for Electrical Panels

Clear terminal identification is essential for efficient assembly, commissioning, troubleshooting and maintenance of electrical control systems. The TE Connectivity RC55 marking system provides a practical method of applying consistent identification to compatible terminal arrangements, helping engineers and technicians quickly recognise circuit functions and connection points.

The pre-printed L1-L2-L3-N-PE sequence is particularly useful for three-phase power distribution applications, identifying the three line conductors together with neutral and protective earth connections. By supplying these markings in a ready-to-use horizontal format, the 1SNA230131R2500 helps create neat, standardised terminal assemblies while reducing manual marking work.

Typical Applications

• Three-phase electrical distribution panels.
• Industrial control cabinets and switchboards.
• Terminal block and terminal strip identification.
• Machine control and automation panels.
• Motor control centres and power distribution equipment.
• OEM electrical panel building.
• Industrial maintenance and replacement marking.
