{"product_id":"littelfuse-se-330hv-07-00","title":"Littelfuse SE-330HV-07-00","description":"The SE-330 is an advanced ground-fault and neutral-grounding-resistor monitoring relay. It measures neutral current, neutral-to-ground voltage, and neutral-to-ground resistance. It provides continuous monitoring of the neutral-to-ground path to verify that the neutral-grounding resistor (NGR) is intact. This is of utmost importance—an open NGR renders current-sensing ground-fault protection inoperative and could result in a false belief that the system is functioning properly. The SE-330 can be used with low- and medium-voltage transformers and generators with low- or high-resistance grounding used in processing, manufacturing, chemical, pulp and paper, petroleum, and water-treatment facilities. For high-voltage applications, use the SE-330HV. For applications that require conformance to Australian standard AS\/NZS 2081.3:2002, see the SE-330AU.SE-330HV-07-00 - SE-330HV Series\u003cp\u003e\u003cstrong\u003eLittelfuse SE-330HV-07-00 is now available from Williams Automation.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf you need a specific firmware version or series for this item, please call or email us with your request.
