Why Choose the TE Connectivity ENTRELEC RC55 1SNA230021R2200 Marker Card?

The TE Connectivity ENTRELEC 1SNA230021R2200 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 191 to 200 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 1SNA230021R2200 provides 100 individual markers arranged as ten repeated sequences from 191 through 200, helping panel builders and electrical engineers create consistent and easily readable terminal assemblies.

The RC55 format uses 5 mm spacing and is designed for professional terminal identification applications. The 1SNA230021R2200 features a white marker surface, horizontal coding direction and a card weight of approximately 2.7 g, providing a practical marking solution for industrial electrical panels and automation equipment.
