Weidmüller part number 2428540000 (A3T 2.5 VL) is a multi-tier modular feed-through terminal block with PUSH IN connection technology, rated 2.5 mm², 800 V, 24 A. Unlike the standard A3T 2.5, its three levels are internally cross-connected into a single potential, making it a compact power/signal distribution terminal on one DIN rail footprint.

Applications
Suited for compact single-potential distribution on a DIN rail — for example, feeding a common supply or signal to multiple downstream points — where the internally bridged 3-level design saves wiring compared to separate jumper bars.
