The 07.311.2953.8 is a partition plate with marking facility designed for use with Wieland Electric DIN rail-mounted terminal block systems. This yellow-colored accessory is specifically engineered to divide and organize terminal block circuits while providing a marking surface for circuit identification and labeling. The partition plate is compatible with multi-tier terminal block configurations, including WKM 4/15 and similar block types, and mounts directly onto TS 35 DIN rails (35 × 27 × 7.5 mm or 35 × 27 × 15 mm per EN 60715). It facilitates clear circuit identification in electrical installations by allowing operators to mark and separate different circuit groups, improving safety and maintenance efficiency in control panels and distribution systems.
