Clēēr™ 600 A Loadbreak Connector System

cleer-600A-loadbreak.jpg

Clēēr™ Loadbreak Connector reduces outages by providing reliable switching under load – as reliable as traditional 200 A loadbreak connectors – and allows other circuits to remain energized, limiting the amount of downtime and inconvenienced customers.

It is the only 600 A three-phase rated loadbreak connector system in the industry. Available in 15, 25 and 28 kV ratings, this unique solution offers both a visible break and visible ground without having to de-energize, unbolt 600 A terminations, or move heavy cables. This system offers an efficient and reliable visible break when used for sectionalizing, splicing, or in-line with vacuum switchgear.

Features

  • The C-shaped connector breaks the circuit in two places for twice the contact separation.
  • The new Clēēr Loadbreak Connector incorporates field-proven Cooper Power Systems POSI-BREAK™ technology which provides:
    • Increased strike distance, greatly reducing the possibility of partial vacuum flashovers
    • Added dielectric strength along the probes for superior switching performance and reliability
  • The remainder of this simple system consists of:
    • Two Cooper Power Systems 600 A loadbreak interfaces
    • Two IEEE Std 386™-2006 standard 600 A deadbreak interfaces
  • A yellow latch indicator is included to assure positive connection
  • Fully submersible, and exceeds the applicable requirements of IEEE Std 386™-2006 standard for use in above- and underground environments prone to flooding
  • When using BT-TAP or T-OP II connectors a visible ground can be achieved by connecting a grounding elbow directly to a 200 A loadbreak reducing tap plug.
