Applications
|
| Three Phase Surge Arrester for 208, 220,
240 VAC - both commercial and industrial usage. Installed at wattmeter,
service entry or weatherhead, safety clamps and dissipates lightning
induced AC line high voltage current impulses going to a residence,
apartment or a light industrial building. |

Description
|
| Introducing the TES 208 SE Surge Arrester,
installed at wattmeter, locations for commercial and industrial applications.
The TES 208 SE Surge Arrester is specifically designed for long lifetimes
even with strong lightning activity and temporary line overvoltage
conditions. A tough Surge Arrester for tough line conditions.. |
|
|
Features
|
- 40,000 Amp peak capability, each phase
- Temporary overvoltage clamping capability.
- Lowest, reliable voltage clamping level
- Safety fusing, all phases, patented
- LED "unit good" indicators, all phases
- Fire proof and explosion-proof polycarbonate glassfiber reinforced
enclosure with matching mounting connector
- Sealed units except for mounting connector wiring opening
- For less inductance, #10 AWG tinned wires.
- Competitive pricing

|
| Accelerated Life Test - look
at the
test results and the guidelines
for testing of TESCO products. |
Surge Arrester still in excellent condition
at end of tests. No arcing.
|
| Temporary Overvoltage - continuous,
5 minutes, maximum line voltage without thermal runaway.
|
210VAC
|
| End of Life Failure Mode
While in overvoltage induced thermal runaway, apply 7kA
at operating voltage. Surge arrester must fail safe without
faulting the AC line. No arcing allowed.
