Why Choose the TE Connectivity RC410 21–30 Horizontal Marker Card?

The TE Connectivity RC410, part number 1SNA229004R0500, is a white pre-printed terminal block marker card designed for identifying compatible Entrelec SNA and Solution series terminal blocks. It is supplied with horizontal number markings covering 21 to 30, repeated across ten marking strips for efficient panel identification.

With a 4 mm marking pitch, the RC410 system is particularly suited to compatible spring-clamp terminal blocks and screw-clamp miniblocks. Pre-printed identification eliminates the need to print individual terminal markers on site, helping panel builders achieve clear, consistent and professional terminal-strip labelling.

The marker card is manufactured from white polyamide with a UL94 V-2 flammability classification. Its horizontal printing orientation makes terminal numbers easy to read in the intended mounting arrangement, supporting efficient commissioning, inspection, troubleshooting and maintenance of industrial electrical panels.

Key Advantages

• Pre-printed 21–30 numbering saves terminal identification and printing time.

Reliable Terminal Identification for Industrial Panel Wiring

Clear terminal identification is essential for efficient installation, commissioning and maintenance of electrical control systems. The RC410 pre-printed marker card provides a consistent sequence of 21 to 30, avoiding handwritten labels and reducing the time required to produce individual terminal markings.

The 4 mm pitch RC410 system is designed for compatible Entrelec terminal blocks, including spring-clamp terminals and screw-clamp miniblocks within the SNA and Solution ranges. Its repeated pre-printed strips make it particularly useful when the same numbering sequence is required across several terminal assemblies or control panels.

Typical Applications

• Industrial control panel terminal identification.
• PLC and automation cabinet labelling.
• Entrelec SNA terminal block assemblies.
• Compatible spring-clamp terminal blocks.
• Compatible screw-clamp miniblocks.
• Machine-building and OEM electrical panels.
• Switchgear and distribution equipment.
• Maintenance and refurbishment of existing Entrelec terminal strips.
