It features pre-printed numbering from 21 to 30 with 6 mm pitch spacing, compatible with Wieland terminal block systems including WKI, WKIF, WK, WKN, and 9700 A series blocks. The strip is supplied in standard packs of 25 units and is intended for use with terminal blocks rated at 800 V/8 kV/3 (per EN 60947-7-1) and 600 V (UL/CSA ratings). This marking strip enables clear circuit identification and organization in multi-circuit installations, particularly in three-phase electrical systems with neutral and ground connections, improving safety and maintenance efficiency in industrial and commercial wiring applications.
