Indoor Low-Voltage Single-Phase Potential Transformers
PT as Auxiliary Power Source (Select Models)
About the Product
S-N Series low-voltage single-phase potential transformers, intended for usage in indoor locations of lower humidity, are insulated with a Class-A insulation material. These PTs can be used in conjuction with measuring or monitoring instruments, or as an auxiliary power source in the main panel or motor control panel.
- Standard: IEC, CNS, or IEEE
- Suited to locations with lower humidity
- Economical, compact and easy to install
- Terminal covers included for prevention against electrical shock
* Other standards and specifications available.
** If burden rating > 500VA, the PT can be used as an auxiliary power source (accuracy N/A)
S-5N, S-6N, S-7N, S-8N, S-9N, S-10N, S-11N, S-12N
