Epoxy-encapsulated coils777Application DescriptionTransformers providestepped-down voltages tomachine tool control devices,enabling control circuits tobe isolated from all powerand lighting circuits. Thisallows the use of groundedor ungrounded circuits thatare independent of the poweror lighting grounds; thus,greater safety is affordedthe operator. The controltransformer line is particularlyadaptable on applicationswhere compact constructionis demanded.Note: The MTG “open core-coildesign” has been superseded bythe epoxy-encapsulated core-coildesign MTE with no change todimensions or functionality.77Features, Benefitsand Functions 77 7Epoxy encapsulatedLaminations of high-qualitysilicon steel to minimizecore losses and optimizeperformanceCopper magnet wire forhigh-quality, efficientoperationSecondary fuse clipswhere applicableOptional primary fusingMoulded in terminals50/60 Hz operation130 C insulationsystem standardPerformance meets/exceeds requirementsof ANSI/NEMA ST-1Regulation exceedsANSI/NEMA requirementsfor all ratings25–1500 VA ratingsMoulded-in terminals formaximum durability777777V7-T7-4Volume 7—Power Control Products CA033001EN—January 2017 www.eatoncanada.caStandards and Certifications UL listedcUL listedRoHS compliantIndustry StandardsAll Eaton dry-type distributionand control transformers arebuilt and tested in accordancewith applicable NEMA, ANSIand IEEE Standards.
