* Ratings given are for service conditions within temperature and altitude limitations as defined by IEEE C37.20.2-2015 metal-clad standard.
** 4000 A is forced-air cooled.
For 5 kV applications, SafeGear switchgear utilizes
ABB VIY-60 potential transformers. For 15 kV appli-
cations, SafeGear uses ABB VIZ-11 and VIZ-75 PTs. All
PTs are available in wye-wye, open delta, line to line
and line to ground connections.
Rating tables and additional details for all instru-
ment transformers can be found in the Switchgear
Components and Accessories Technical and Appli-
cations Guide (1VAL104601-TG)
