The TE Connectivity 1546670-8 is an 8-circuit Buchanan series barrier strip with 0.437" (11.10mm) pitch, rated 25A at 300V. This is the terminal block you reach for when a ring lug under a screw is the only termination you trust — no push-in spring to argue with, no ferrule to second-guess. The dual-wall (2 Wall) barrier construction puts an extra wall of thermoplastic between adjacent terminals, which matters when the panel gets damp and you need the creepage distance to hold. Accepts 14-22 AWG wire, so it covers everything from a 14 AWG motor lead down to a 22 AWG control signal.
The 25A Rating and What It Buys You
25A per circuit is bus-level current for a barrier block this size — it's not a signal-line terminal. That rating holds across the full 14-22 AWG range, and the 300V ceiling covers standard 277/480V industrial control voltages with margin. The steel screws with nickel finish take a ring or spade lug without galling, and the closed bottom means no solder tails or PCB pins — this block lands on a chassis or panel, not a board.
Mounting and Environment
Mounting flanges let you bolt this block to a panel or chassis — no DIN rail adapter needed, no plastic clips to break.
