Three-Level Spring Cage Terminal Blocks

The three-level spring cage terminal block ST 2,5-3L has three feed-through levels in a 5 mm wide terminal housing. It offers high wiring density, which is especially important when switchgear space is restricted. With one bridge shaft on each level, this modular terminal block can be used as a compact potential distributor or as a sensor terminal, for example. All six terminal points are interconnected in the variant ST 2,5-3PV. This potential distributor is identified by an imprint on the terminal housing. The three-level terminal block range is rounded off by a ground terminal of the same shape. The ST 2,5-PE/L/N and ST 2,5-PE/L/L variants have a PE contact to the mounting rail in the lower level and two feed-through levels. The three-level terminal blocks can be labeled on each level. Large-surface labeling of the three levels is also possible using the three-way marker carrier STP 5-3.
