Screw-Clamp Terminal Block for Panel Wiring
The TE Connectivity Buchanan 1437651-2 is a screw-type terminal block — a fixed clamp designed for secure wire termination in control cabinets, junction boxes, and distribution panels. The screw mechanism applies direct clamping force to the conductor, which is the standard for field-installed power and signal wiring where vibration resistance and pull-out retention are required. It belongs to the Buchanan series, a long-running family of barrier-style and screw-clamp blocks used across industrial and commercial electrical installations.
Compatibility and Cross-Reference
This terminal block is listed for use with the #6, BC6, JC6, MB6, and NC6 series — these are the mating barrier strips, jumpers, and accessories that share the same screw-clamp footprint and pitch. No official cross-reference to a different manufacturer part is on record; the Buchanan series is the direct replacement path within the TE Connectivity catalog.
The Bulk package suits panel builders and maintenance stock who need a quantity of identical blocks for a single job.
