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.
- 15 KV : 110 kV BIL
- 27 KV : 125 kV BIL
- 27 KV : 150 kV BIL
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

Pressure Relief Valves
ANSI and REA Standards specify pressure relief valves for oil filled equipment.Details
The Heartland pressure relief valve relieves excessive pressure in transformers, regulators and other electrical equipment.
- 5 PSI : 35 SCFM
- 10 PSI : 35 SCFM
- 10 PSI : 50 SCFM
- 10 PSI : 60 SCFM
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.
Standards: The IFD conforms to: IEEE C57.12.20, CSA C2.2, IEC 61936-1Details
GreenCap® Series now makes easy to distinguish the NEB fluid filled transformers from the Mineral Oil filled transformers.Details
