Operation range 3 kV to 36 kVDetails
Line crews need not be exposed to high voltage conductors and hot transformer fluidsDetails
Externally operated one-, two- and three-phase under-oil tap changer switch family eliminates many of the hazards associated with manual internal tap changing of distribution transformers.
The MagneX Interrupter combines safety and efficiency with economic operation.Details
One, Two & Three-Phase Magnex Interrupter. The magnex Interrupter protects distribution transformers from overloads and secondary faults. It can also be utilized as a transformer turn on-off switch.

Exceeds protective levels offered by standard metal oxide varistor arresters.Details
Heavy-duty Distribution Class Under-oil MOV ArresterDetails
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.
- 3 KV To 27 KV : 2.55 kV To 22 kV MCOV
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.
- 175 V : 175 V MCOV
- 240 V : 240 V MCOV
- 480 V : 400 V MCOV
- 650 V : 540V MCOV
IEC Distribution Arrester Class 1
Operation range 3 kV To 36 kVDetails
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
Used to avoid re-energize faulted transformers.Details
Used in series with a Bay-O-Net type fuse or MagneX Interrupter. Isolation links are not fuses and do not have an interrupting rating. During a transformer failure, the isolation link will melt so that the opened primary circuit of a faulted transformer cannot be re-energized by the line crew.
ELSP Current-limiting Backup Fuse
Used in series with low current primary protection devices.Details
The ELSP fuse is designed for use in transformer oil, Envirotemp FR3 fluid, or an approved equivalent. The fuses highly efficient current limiting section minimizes the effects of high fault current stresses on equipment and the distribution system.
- 8.3 To 23 KV : 30 To 330 A
- 15.5 KV : 30 To 300A
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
Low Voltage Breakers
Designed to minimise the electrical losses incurred in the breakerDetails
Samrakshana breaker provides overload and short circuit protection for both pad mounted and pole type transformers. Wall mounting. The bimetal element is mounted as close as possible to the top oil level, permitting maximum thermal protection.
- Single Phase : 5 to 50 kVA
- Three Phase : 15 to 75 kVA
