The 284051-4 is a 4-position, single-level plug with female sockets from the TE Buchanan series — a free-hanging (in-line) connector that mates with a matching header on a panel or PCB. At 15 A per position with a 300 V rating, this plug handles branch-circuit power in industrial control panels, distribution blocks, and HVAC equipment. The 90° wire entry routes conductors parallel to the panel face — useful when enclosure depth is limited and the cable bundle needs to run flat against the backplane.
Termination and wire range — screwdriver work, not crimp tool
For environments with repeated disconnect/reconnect, gold-plated contacts would offer longer cycle life, but tin keeps the per-unit cost down for fixed installations.
Temperature range and environmental limits
This covers outdoor cabinets, near-motor compartments, and unheated storage areas.
