Why Choose the TE Connectivity RC55 1SNA230150R1400 Terminal Block Markers?

The TE Connectivity 1SNA230150R1400 is an RC55 pre-printed terminal block marker card designed for clear, consistent identification of terminals in electrical control panels, switchgear and industrial automation systems. Part of the TE Connectivity ENTRELEC RC55 marking range, this version contains 100 markers printed with the letter A for horizontal terminal identification.

Designed for compatible ENTRELEC SNA and Solution series terminal blocks, the RC55 marker system provides an efficient alternative to individually preparing identification labels. The pre-printed format enables panel builders to apply repeated letter identification quickly and consistently, helping simplify installation, circuit tracing, commissioning and maintenance.

The 1SNA230150R1400 features 5 mm spacing, a white marker surface and durable polyamide construction. It is configured for horizontal mounting and carries a UL 94V-2 flammability rating, making it a practical identification accessory for professional industrial electrical assemblies.

Reliable Terminal Identification for Industrial Panels

Clear terminal identification is important for efficient electrical panel construction, commissioning, fault finding and ongoing maintenance. Pre-printed RC55 markers provide a consistent identification method while reducing the preparation required compared with producing individual labels for every terminal position.

The RC55 1SNA230150R1400 is particularly useful where the letter A needs to be repeated across multiple terminals or connection points. With 100 identical markers on one card and a 5 mm format for horizontal mounting, it supports organised identification across compatible ENTRELEC terminal assemblies.

Typical Applications

• Industrial electrical control panels.
• Terminal block and connection-point identification.
• PLC and automation cabinets.
• Switchgear and distribution assemblies.
• Machine control and production equipment.
• OEM electrical panel manufacturing.
