Rated 20 A at 300 V, it accepts wire from 12 to 30 AWG, with a stripping length of 8 mm. ## Lifecycle and Sourcing — 125-BU Is Obsolete The 125-BU is officially obsolete per the manufacturer's lifecycle status. No direct replacement order code is listed from TE Connectivity. ## What It Fits — Dimensions and Mounting The body measures 0.880\" (22.35 mm) in length and 0.810\" (20.57 mm) in height, with a terminal width of 13.2 mm. It mounts directly to a panel or enclosure wall — no DIN rail adapter. The single-level, 2-position layout is a straightforward inline barrier strip for two-wire termination, common in power distribution or control signal pass-through. The tubular clamp termination accepts solid or stranded wire without a ferrule — the clamp wraps around the conductor, distributing clamping force evenly. For field-service replacement, the 8 mm strip length is the critical dimension: strip too short and the clamp misses the conductor; strip too long and bare wire is exposed past the insulator.","metaTitle":"TE Connectivity 125-BU Terminal Block, 2 Pos, 20 A, 300 V","metaDescription":"TE Connectivity Buchanan 125-BU NEMA open construction terminal block, 2 positions, 20 A, 300 V.
