PGR-5330-00-00 - PGR-5330 Series

Series: PGR-5330      Obsolete: 2013-09-06 Questions? Contact Littelfuse Support

Replaced by: SE-330

The PGR-5330 is an advanced ground-fault and resistor monitoring relay. The PGR-5330 measures neutral current, neutral-to-ground voltage and neutral resistance. It provides continuous monitoring of the neutral-to-ground path to ensure the neutral-grounding resistor (NGR) is intact. This is of utmost importance on resistance-grounded systems because NGR failure renders current-sensing ground-fault protection inoperative.

Version 2.1

pdf icon SE-330 Manual - Previous Revision

A high-resistance-grounded system uses a neutral- grounding resistor (NGR) with a low let-through current to limit ground-fault current.
