Details
This type L cutouts are available in both polymer and porcelain designs, which provide reliable overcurrent protection for primary distribution circuits. Overcurrent protection safeguards an electric system from excessive currents produced by abnormal conditions such as faults, line or equipment overloads, or equipment failures.

Bayonet Fuses
To protect distribution apparatus from damaging currents and to protect distribution systems from failed apparatus.
Details
Its ideal use is in a two-fuse protection scheme with a current-limiting backup fuse. In this arrangement, secondary faults and overload currents are cleared by the Bay-O-Net fuse, and high level faults are cleared by the current-limiting fuse. The two fuses are connected in series

Evolution Arrester
Exceeds protective levels offered by standard metal oxide varistor arresters.
Details
The Evolution surge arrester uses specially formulated and highly durable Metal Oxide Varistors (MOVs) in combination with a proprietary insulating ceramic ring assembly.
-
Under-oil MOV arrester is designed in accordance with ANSI/IEEE C62.11 heavy-duty distribution class requirements. It is designed for either horizontal or vertical mounting inside the distribution transformer tank to eliminate the difficulties associated with externally mounted arresters.
-
Low Voltage Arrester
Is available in three design configurations: external mount, metal enclosed, and internal mount.
Details
StormTrapper H.E. (High Energy), low voltage distribution class surge arresters are designed to provide surge protection at distribution transformer secondary bushings, service entrance locations, and any other electrical apparatus connected to a secondary voltage source.

Dual voltage
line crews need not be exposed to high-voltage conductors and hot transformer fluids.
Details
Externally operated series multiple switch is used to change connection of de-energized transformer windings between series and parallel to provide different common transformer voltage ratios.
-
The IFDTM is a sensor that detects internal arcing faults in distribution transformers. The sensor releases a highly visible orange signal that shows the line worker the transformer status before re-energizing.
-
GreenCap Valves
GreenCap® Series now makes easy to distinguish the NEB fluid filled transformers from the Mineral Oil filled transformers.
Details
This valve is designed specially to be used in transformers filled with natural ester fluids such as the FR3. Ensures compatibility and flow requirements for these fluids.
