Clēēr™ 600 A Loadbreak Connector System
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.
| Continuous Current | 600 A rms |
| Loadbreak Switching (15 kV, 25 kV, 28 kV) | (15 kV) Ten make and break operations at 600 A at 14.4 kV Phase-Phase. (25 kV) Five make and break operations at 600 A at 26.3 kV Phase-Phase. (28 kV) Five make and break operations at 600 A at 28.0 kV Phase-Phase. |
| Loadbreak Switching (15 kV, 25 kV, 28 kV) | (15 kV) Three make and break operations at 900 A at 14.4 kV Phase-Phase. (25 kV) One make and break operation at 900 A at 26.3 kV Phase-Phase. (28 kV) One make and break operation at 900 A at 28.0 kV Phase-Phase. |
| Fault Closure (15 kV, 25 kV, 28 kV) | (15 kV) 16 kA rms symmetrical at 14.4 kV Phase-Phase after ten 600 A loadbreak switching operations for 0.17 seconds. (25 kV) 10 kA rms symmetrical at 26.3 kV Phase-Phase after five 600 A loadbreak switching operations for 0.17 seconds. (28 kV) 10 kA rms symmetrical at 28.0 kV Phase-Phase after five 600 A loadbreak switching operations for 0.17 seconds. |
| Fault Closure (15 kV, 25 kV, 28 kV) | (15 kV) 16 kA rms symmetrical at 14.4 kV Phase-Phase after three 900 A loadbreak switching operations for 0.17 seconds. (25 kV) 10 kA rms symmetrical at 26.3 kV Phase-Phase after one 900 A loadbreak switching operation for 0.17 seconds. (28 kV) 10 kA rms symmetrical at 28.0 kV Phase-Phase after one 900 A loadbreak switching operation for 0.17 seconds. |
| 4 Hour Overload Current | 900 A rms |
| Short Time Current (15 kV, 25 kV, 28 kV) | (15 kV) 16 kA rms symmetrical for 0.17 seconds (limited by fault closure rating). (25 and 28 kV) 10 kA rms symmetrical for 0.17 seconds (limited by fault closure rating). |
| Short Time Current | 10 kA rms symmetrical for 3.0 seconds |
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.
