Cutouts

Eaton’s Cooper Power series distribution class cutouts are available in a variety of types: universal, arrester combinations and loadbreak types. All cutouts provide reliable overcurrent protection for primary distribution systems. Overcurrent protection safeguards an electric system from excessive currents produced by abnormal conditions such as line faults, line or equipment overloads or equipment failure. For the ultimate in reliability and dependability, Cooper Power series cutouts provide superior performance in harsh climates, including reduced cracking and breakage.

Core features

  • The porcelain Type L cutout is designed with a solid core, birdproof, one-piece porcelain frame with uniform shed configuration
  • The backbone of the UltraSIL polymer-insulated Type L cutout is comprised of an E-glass fibreglass rod with crimped-on galvanised steel hanger and end fittings
  • The cast bronze lower hinge assembly has deep pockets for the trunnion to pivot to minimize accidental fuse removal
  • Loadbreak cutout consists of a heavy-duty arc reducing load interrupter mounted to the cutout frame. The interrupter together with the associated fuse holder provides a safe, reliable, loadbreaking device with visible break
  • Combining the functions of a distribution-class surge arrester with a fuse cutout provides the convenience of a compact, efficient unit with less pole-top hardware. Combining these units also provides easier installation, handling and procurement
  • Fuseholders are interchangeable with polymer and porcelain cutouts manufactured by S & C Electric Co. (Type XS), A.B. Chance Co. (Type C) and ABB (Type ICX)
