1sna237043r2300 – rcal85 10x(21a30) vert,

Why Choose the TE Connectivity RCAL85 1SNA237043R2300 Terminal Block Markers?

The TE Connectivity RCAL85 1SNA237043R2300 is a set of pre-printed terminal block markers designed for clear and consistent identification of electrical connections in industrial control panels and automation systems. Part of the established RCAL85 marking range, this version is pre-printed with numbers 21 to 30 repeated ten times and is intended for vertical terminal block assemblies.

RCAL85 markers provide a convenient alternative to individually printing terminal identification labels, helping reduce preparation time during panel building, installation and maintenance. The markers are designed for use with compatible spring-clamp terminal blocks and ADO System® Miniblocks from the SNA and Solution series, providing organised identification throughout terminal assemblies.

The 1SNA237043R2300 uses 8 mm marker spacing and is manufactured from white polyamide with a V2 flammability classification. Its pre-printed 21–30 numbering sequence and vertical orientation make it particularly suitable for structured terminal identification in switchboards, machinery control cabinets and industrial electrical installations.

Clear Identification for Industrial Terminal Assemblies

Accurate terminal identification is essential when assembling, commissioning and maintaining industrial electrical equipment. Pre-printed RCAL85 markers provide a consistent numbering system that helps engineers quickly identify individual connection points, reducing the time required to trace wiring during installation, inspection and fault finding.

The RCAL85 range is designed for compatible SNA and Solution series terminal blocks, including spring-clamp terminals and ADO System® Miniblocks. The pre-printed format is particularly useful for repetitive panel-building applications where standard terminal numbering sequences are required across multiple assemblies.

Typical Applications

• Industrial electrical control panels.
• Terminal block identification.
• PLC and automation cabinets.
• Machinery control systems.
• Switchboards and distribution panels.
• OEM panel building and electrical assembly.
