It steps a 300 A primary current down to a standard 5 A secondary output and is available in two accuracy classes, making it a practical choice for retrofitting current measurement into existing panels and switchboards.\u003c\/p\u003e\u003cp\u003eTechnical specifications:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eModel: TP8 300\/5\u003c\/li\u003e\n\u003cli\u003eCircutor code: M78025\u003c\/li\u003e\n\u003cli\u003eEAN: 8433059401412\u003c\/li\u003e\n\u003cli\u003eTransformer type: Split core\u003c\/li\u003e\n\u003cli\u003eSystem: Single-phase\u003c\/li\u003e\n\u003cli\u003eMeasurement range: 300\/5 A\u003c\/li\u003e\n\u003cli\u003eFlat strip (busbar) aperture: 60 x 80 mm\u003c\/li\u003e\n\u003cli\u003eInner diameter: 60 mm\u003c\/li\u003e\n\u003cli\u003eRated burden by accuracy class: Class 1 at 1 VA, Class 3 at 2.5 VA\u003c\/li\u003e\n\u003cli\u003eSafety factor (SF): 10\u003c\/li\u003e\n\u003cli\u003eInsulation voltage between terminals S1-S2: 3 kV\u003c\/li\u003e\n\u003cli\u003eMaximum operating voltage: 0.72 kV AC\u003c\/li\u003e\n\u003cli\u003eNominal frequency: 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003eThermal short-circuit current (Ith): 60 In\u003c\/li\u003e\n\u003cli\u003eDynamic current (Idyn): 2.5 Ith\u003c\/li\u003e\n\u003cli\u003eDimensions (width x height x depth): 138 x 51 x 154.8 mm\u003c\/li\u003e\n\u003cli\u003eEnclosure: Self-extinguishing plastic, class V0\u003c\/li\u003e\n\u003cli\u003eMounting: Wall-mounted or DIN rail (via accessory)\u003c\/li\u003e\n\u003cli\u003eWeight: 0.55 kg\u003c\/li\u003e\n\u003cli\u003eThermal class: B (130 °C)\u003c\/li\u003e\n\u003cli\u003eProtection class: IP 20\u003c\/li\u003e\n\u003cli\u003eWorking temperature: -5 to +40 °C\u003c\/li\u003e\n\u003cli\u003eStorage temperature: -40 to +85 °C\u003c\/li\u003e\n\u003cli\u003eRelative humidity: 15 to 85% (non-condensing)\u003c\/li\u003e\n\u003cli\u003eMaximum installation altitude: 1000 m\u003c\/li\u003e\n\u003cli\u003eStandards: UNE-EN 61869-1, UNE-EN 61869-2, UL 94\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFeatures and benefits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSplit core design lets the transformer be fitted around live cables or busbars without cutting power, removing the need for planned outages during installation.\u003c\/li\u003e\n\u003cli\u003eWide 60 x 80 mm aperture accommodates the flat busbars and large-section conductors common in high-current distribution systems.\u003c\/li\u003e\n\u003cli\u003eTwo selectable accuracy classes (1 and 3) allow the unit to be matched to general metering or load monitoring applications.\u003c\/li\u003e\n\u003cli\u003eSelf-extinguishing V0 enclosure limits fire propagation risk inside electrical panels and switchgear cabinets.\u003c\/li\u003e\n\u003cli\u003eDual-frequency rating (50\/60 Hz) makes the transformer suitable for use in both European and international power systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eApplications:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRetrofitting current sensing into energised distribution boards and motor control centres without service interruption.\u003c\/li\u003e\n\u003cli\u003eEnergy metering and consumption monitoring on 300 A single-phase circuits in industrial and commercial buildings.\u003c\/li\u003e\n\u003cli\u003eProviding a 5 A secondary signal to power analysers, multifunction meters, and protection relays.\u003c\/li\u003e\n\u003cli\u003eCurrent measurement on flat busbar installations in switchboards where dismantling is impractical.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAlso known as: Circutor TP8 300\/5, TP8 300\/5 M78025, split core current transformer 300 A, Circutor M78025, split core CT 300\/5 A.\u003c\/p\u003e","brand":"CIRCUTOR","offers":[{"title":"Default Title","offer_id":58138763624712,"sku":"CRCM78025","price":65.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/4351\/3096\/files\/circutor-m78025-tp8-split-core-current-transformer-3005a-60x80mm-4296119.jpg?v=1783036994","url":"https:\/\/gabbyelectric.com\/en-us\/products\/circutor-m78025-tp8-split-core-current-transformer-300-5a-60x80mm","provider":"Gabby Electric","version":"1.0","type":"link"}
