EC: Modular Knifeblade Fuse Blocks
Power - Energy, power interruption: Industry's first modular fuse blocks for Class H (K), R, and J fuses 70 A to 600 A make installation easy and increase flexibility and electrical safety. This is a Control Engineering 2013 Engineers' Choice finalist.
Offering greater application flexibility and enhanced safety, the new Class R, H(K) and J modular knifeblade fuse blocks from Cooper Bussmann feature an innovative snap-together design for easy assembly of required poles at point of application. Available with optional high-clarity finger-safe covers across the entire product line, they are ideal for panel builders, processing and machinery plants, as well as HVAC and critical power applications.
The all new knifeblade fuse blocks offer a set of advantages unmatched in the industry. In addition to the snap-together one-pole versions, factory assembled two- and three-pole configurations are available. Optional high-clarity, see-through, finger-safe covers feature test probe holes, making routine maintenance safe, quick and easy. Wire terminations inspections or thermography measurements are done without ever opening the cover. Built-in standard barriers between poles further enhance safety.
In addition to modularity and safety, the new knifeblade fuse blocks also offer the industry's best ratings. Ahead of the competition, all fuse blocks meet UL creep and clearance requirements for Industrial Circuits (UL508, UL845). Additionally, blocks rated 200 A and above also meet the higher UL Industrial Power Distribution Standards (UL98, UL67, UL489, UL891 and UL869A). Additional benefits of choosing the new Cooper Bussmann knifeblade fuse blocks include a lockout/tagout feature on the covers that improves safety, finger-safe wire entry cutout tabs for larger wires, and an optional blown fuse indicator on the covers that speeds up troubleshooting.
