Trans-Guard FX |
|
Full-Range Type Current-Limiting |
|
Fuses for Distribution Equipment Protection |
|
General: |
|
The Trans-Guard FX full-range current-limiting fuse provides both overload and short circuit |
|
protection with a single fuse. The Trans-Guard FX line can be installed in "Dry-Well" canisters for |
|
distribution transformer protection, in clip mounts on live-front transformer and switchgear |
|
equipment, and either on or adjacent to equipment on overhead distribution systems. These fuses |
|
can also be installed directly submerged in oil, or they can be encapsulated in rubber for "dead- |
|
front" mounting. |
|
Design Features: |
||
|
|
ü |
High fault current interrupting capability (50,000 amperes symmetrical) |
|
|
ü |
Broad range of ratings available, compatible with existing industry standard sizes and |
|
|
|
mountings |
|
|
ü |
Patented Damage SensorÒ designed to significantly reduce the risk of fuse failure |
|
|
|
should the fuse be subjected to an element damaging current surge |
|
|
ü |
Hermetically sealed construction ensures that no gases escape from the fuse during |
|
|
current interruption and that a fuse's performance will not be adversely affected in dry- |
|
|
|
well canister applications, should the canister develop an oil leak. All Trans-Guard FX |
|
| fuses are helium mass spectrometer leak tested to ensure sealing system integrity. | ||
|
New! |
ü |
Optional blown fuse indicator provides reliable indication of fuse operation without |
|
|
adversely affecting the fuse's arcing performance due to its unique design |
|
|
ü |
Rugged machined brass end caps used for greater ferrule strength, resulting in less |
|
|
|
distortion and more secure fuse attachment in dry-well canisters |
|
|
ü |
Tested in accordance with the most recent ANSI/IEEE standards, which include |
|
|
|
requirements for short circuit testing at the manufacturer's specified rated maximum |
|
|
|
application temperature (140°C and 71°C for 2.2 inch and 3.3 inch diameter |
|
|
|
Trans-Guard FX designs, respectively. |
