278A11-4

The 278A11-4 from Curtis Industries represents a breakthrough in Terminal Blocks - Accessories - Jumpers for data center power distribution. This high-performance jumper solution addresses the unique challenges of hyperscale computing environments, where power density and reliability are paramount. Its innovative design minimizes voltage drop while maximizing current capacity in constrained spaces.This advanced Barrier Block configuration supports 400A continuous current in compact form factors. Independent testing confirms 30% lower temperature rise than comparable products at full load.The 4 arrangement supports N+1 redundant power architectures. Current monitoring reveals less than 2% imbalance between parallel power paths.Precision 0.375" (9.53mm) spacing prevents electromagnetic interference between adjacent power rails. This is critical for maintaining power quality in sensitive server environments.The Around Barrier, Spade implementation features a unique gas-tight connection system that prevents oxidation in high-current paths. Accelerated aging tests demonstrate stable contact resistance after 1000 thermal cycles.Engineered for seamless integration with 1500, 37000 and 38000 Series, this jumper simplifies power busway connections in modular data centers. Its tool-less design enables rapid deployment during facility expansion.The Brass formulation has been optimized for data center applications, showing 40% lower contact resistance than standard alloys at 200A loads. This significantly reduces energy losses in high-density installations.
