1sna230020r0500 – rc55 10x(181 a 190) horiz,

Why Choose the TE Connectivity ENTRELEC RC55 1SNA230020R0500 Marker Card?

The TE Connectivity ENTRELEC 1SNA230020R0500 is a pre-printed RC55 terminal block marker card designed for clear and consistent identification of electrical terminals in control panels, switchgear and industrial automation systems. Part of the established ENTRELEC RC55 marking system, this white marker card features terminal numbers 181 to 190 repeated ten times in a horizontal orientation.

Designed to simplify panel wiring and terminal identification, the RC55 system provides ready-to-use pre-printed markers without requiring individual labels to be produced on site. The 1SNA230020R0500 provides 100 individual markers arranged as ten repeated sequences from 181 through 190, helping panel builders and electrical engineers create consistent and easily readable terminal assemblies.

The RC55 format is designed for terminal identification at 5 mm spacing, making it suitable for compatible SNA terminal block installations. With its white marker surface, horizontal coding direction and approximately 2.7 g card weight, the 1SNA230020R0500 provides a practical identification solution for professional panel building and industrial electrical applications.
