22.4Metering Devices, Protective Relays, Software and ConnectivityProtective Relays222222222222222222222222222222222222222222222222222222222222Options and AccessoriesTest Panel (120 Vac)Used to test the ground faultsystem, to give an indicationthe relay has tripped thebreaker, and to reset the relayafter tripping. These functionsmay be separately mountedpilot devices.Note: When a mechanically resetrelay is used with a test panel,both the relay and test panelmust be reset following either asimulated ground fault test oractual ground fault. Not UL listed.Ground Fault Warning IndicatorThis is an accessory item foruse with GFR relays withinterlocking circuitry. Atapproximately 30–50% ofthe relay pickup setting, theindicator switches separate120 Vac control power to aOptional Test PanelGround Fault Warning IndicatorAmmeter KitFace Platelamp or relay (not included) togive an indication of a groundfault. The indicator is rated110/120 Vac 50/60 Hz for amaximum indicator load of0.5 amperes.Indicating AmmeterThe optional indicatingammeter connects to thesensor terminals througha momentary contactpushbutton, and will indicate(in amperes) any ground faultcurrent flowing through thesensor. Kit includes theammeter and pushbutton.Not UL listed.Shunt Trip AttachmentsUse 120 Vac shunt trips.CatalogControlTestNumber120 volt 50/60 Hz 120 volt 50/60 Hz GFRTPDescriptionManual resetSelf-resettingGFR SystemUsed withCatalogNumber1234C67G011234C67G02Kit CatalogNumber1–12 amperes 752B820G015–60 amperes 752B820G02100–1200 amperes 752B820G03DescriptionFace plateCatalogNumber752B410G01NoteOne end removable for installation.Instruction Leaflet 15321 available as a PDF at www.eaton.com (Go to Advanced Search and enter 15321).Face PlateRecommended whenthese relays are semi-flushmounted, to close the doorcutout opening.OptionsAdditional optional equipmentcan be added to the protectionsystem to meet therequirements of the specifyingengineer, including:● Ground fault test panel●Ground fault warningindicator relay●Ground fault indicatingammeterGFR relays are available withzone selective interlockingcircuitry to interlock severalrelays within the samesystem. This allows the relay,which detects a groundfault, to instantly clearthe fault by tripping thedisconnect device. The relaysimultaneously sends a signalto relay units “upstream” fromthe fault to time delay orto block their operationcompletely. Current sensorsin various designs provide arange of “window” sizes toaccommodate standard busand cable arrangements.Shunt trip attachments may beordered for field mounting inEaton’s molded case circuitbreakers, or may be orderedfactory installed in the breaker.376 Volume 3—Power Distribution and Control Assemblies CA08100004E—December 2010 www.eaton.com
