Why Choose the TE Connectivity RC55 1SNA230034R2700 Terminal Block Marker Card?

The TE Connectivity RC55 1SNA230034R2700 is a pre-printed terminal block marker card designed for clear and consistent numerical identification of terminal connections in industrial electrical panels and automation systems. Part of the ENTRELEC RC55 marking range, this version provides the ascending numerical sequence 401 to 500, giving installers 100 consecutively numbered markers in a horizontal format.

RC55 pre-printed markers provide panel builders, machine builders and maintenance engineers with a convenient method of creating uniform terminal identification without individually printing each number. The continuous 401–500 sequence is particularly useful for larger installations where terminals need to correspond clearly with circuit diagrams, wiring schedules and equipment documentation.

Manufactured from white polyamide, the RC55 marking system uses 5 mm spacing and is designed to provide durable, easily readable identification in professional electrical assemblies. The pre-printed format helps streamline panel construction while maintaining consistent numerical coding throughout control and distribution equipment.

Key Advantages

• Provides a complete ascending numerical sequence from 401 to 500.
• Contains 100 consecutively numbered pre-printed markers.
• Horizontal marking format for compatible terminal block assemblies.
• 5 mm spacing for the RC55 terminal marking system.
• White polyamide construction provides durable and clearly visible identification.
• Pre-printed format reduces the time required to create individual terminal labels.
• Supports consistent terminal numbering that can be matched to electrical drawings and wiring documentation.

Sequential Identification for Industrial Terminal Assemblies

Sequential terminal numbering provides an important visual reference between physical electrical connections and the associated circuit documentation. Clearly numbered terminals simplify panel construction and commissioning while helping technicians trace individual connections efficiently during inspection, troubleshooting, modification and maintenance.

The RC55 1SNA230034R2700 supplies every number from 401 through 500 on one pre-printed marker card. This continuous sequence is particularly useful for larger terminal strips and installations that extend into higher terminal numbers, while the horizontal format and 5 mm spacing support orderly and consistent identification.

Typical Applications

• Industrial electrical control panels.
• Sequential terminal block and terminal strip numbering.
• Automation and machinery control cabinets.
• Power distribution assemblies.
• PLC and instrumentation panels.
• OEM machine and panel building.
• Process control installations.
• Electrical maintenance, expansion and retrofit projects.
