Iovative solutios stregthe our existig techology platform, which covers the etire trasmissio ad distributio spectrum. Our Power Techology products rage from trasformers, high voltage ad medium voltage equipmet icludig circuit breakers, idoor paels, istrumet trasformers, discoectios ad capacitors & reactive power compesators. Our mai research i these fields is i ew materials, isulatio, coductio, limitatio ad iterruptio, electromagetic iterferece ad stadardizig electrical systems egieerig. We offer a complete rage of medium voltage equipmet for primary ad secodary distributio with voltages ragig from 1kV up to 40kV. Our portfolio icludes idoor air isulated ad gas isulated paels with vacuum ad SF6 gas circuit breakers, outdoor vacuum ad SF6 gas circuit breakers, auto-reclosers, fuses, switch discoectors, prefabricated modular solutios for power distributio amog others. ABB believes i the importace of iovatio to brig about a better eviromet ad we are developig ew techologies to achieve sigificat resource savigs ad reduced evirometal impact. For example the Dryformer a oil-free, cable-woud power trasformer. To further reduce emissios ad to coserve the world s eergy ad raw material resources, we are strivig to optimize the efficiecy of all eergy-cosumig products ad promote eergysavig techologies. Idustrial IT The VBF circuit breaker is certified as complyig with the ABB idustrial IT architecture. I this architecture VBF circuit breaker is part of the Power IT suite. The products compyig with the Idustrial IT architecture ca be effectively itegrated i a system with high added value ad a true Plug & Produce mode. This product has bee tested ad certified as Idustrial IT Eabled, Level 0 - Iformatio. All product iformatio is supplied i iteractive electroic format, compatible with ABB Aspect Object TM techology. The Idustrial IT commitmet from ABB esures that every eterprise buildig block is equipped with the itegral tools ecessary to istall, operate, ad maitai efficietly throughout the product lifecycle.

Saliet features Desiged ad type tested as per IEC 62271-100/IS:13118 & ANSI C37.09 Vacuum iterruptio Porcelai clad costructio which is suitable for outdoor substatios that provides safety from fire hazards Guarateed for log electrical life with prove vacuum iterrupters utilisig the excellet arc quechig ad isulatig properties of vacuum Restrike free ad suitable for auto closure duty cycle of O-0.3sec-CO-3mi-CO ad CO-15s-CO Miimal operatig eergy required due to simple, reliable ad prove low eergy sprig mechaism used. The mechaism is guarateed for log mechaical life Simple istallatio - structure mouted with a optio to exted structure for moutig istrumet trasformer The complete breaker ca be shipped as oe uit bare miimum adjustmets beig required at site. As a optio the breaker ca be shipped i kocked dow kits ad ca be easily assembled at site. Costructio Pole assembly The pole assembly cosists of 3 poles ad a commo duct. A sigle pole cotais a vacuum bottle, curret trasfer cotacts ad a isulatig pull rod placed i a porcelai housig. The housig provides mechaical stregth, safety from fire hazards as well as evirometal protectio thus makig it suitable for outdoor applicatio. Several primary termial coectors ca be offered, such as NEMA 4. Due to simplicity of desig, spare parts are reduced to miimum. All three poles are mouted o a commo duct placed above the cabiet. Splie shafts of the poles are itercoected to the other poles as well as to the operatig mechaism through suitable likage arragemet. Base cabiet The base cabiet is made of paited mild steel. For harsh evirometal coditios optio of galvaized steel is available, which has higher corrosio resistace. The cabiet houses the sprig operatig mechaism which is mechaically liked to all the three poles. The cabiet also icludes the followig: Rear view with back cover ope 1 2 3 Ati-codesatio heater Circuit breaker status idicator Mechaical operatio couter Breaker cotrol switches 4 5 1 Top Termial 2 Arc Chamber Isulator 3 Vacuum Iterrupter 4 Bottom Termial Ati-pumpig relay 5 Isulatig Rod AC/DC Fuses Auxiliary wirig 6 6 Support Isulator 7 Bottom Crak Housig Termial blocks 7 Sectioal View of Pole Part 3
Operatig mechaism To attai high operatioal reliability ad egligible maiteace, a simple, robust, sprig operated mechaism is used. Features O-C-O operatio without rechargig Closig sprig is charged by motor i less tha 15 secs. Mechaical / electrical ati-pumpig Provisio for maual chargig Suitable for high speed auto reclosig Maual closig ad trippig arragemet Mechaical ON-OFF ad SPRING CHARGED idicatio The operatig mechaism is also provided with the followig optioal items: Auxiliary switch; 6NO+6 NC (stadard): 12 NO+12 NC (Optioal) Additioal trippig soleoid Close-up of Operatig Mechaism with electrical accessories Closig/Opeig coil Auxiliary Switch Sprig Chargig Motor Certified routie test reports Each breaker is tested for the followig routie tests i the factory as per ANSI C 37.09 ad IEC - 62271-100.
