EFO indoor disconnectors are mechanical switches that,used in MV distribution systems for opening and closing of outdoor lines without current.They are producing according to IEC 60129 and IEC 62271-102 with ISO 9001 quality assurance system. EFO M.V outdoor disconnectors have TSE certificates. Technical and Constructional Features:

- Type tests performed acc. to IEC 60129 and IEC 62271-102 - Frame is hot deep galvanized.

- Porcelain and epoxy resin insulators are J type and creepage distance 12 mm/kV

- Fix and moving terminals are made of electrolytic copper and silver plated so power lost minimized.

- Disconnectors are delivered in wooden case with hand drive mechanism.

- There are corrosion resistive materials used between frame and shafts.

- There are double springs where fixed and moving terminals in touch so that contact resistances

are minimized.

- According to customers request earthing switches can be located outgoing or incoming side

Operating of indoor disconnector There is two way of operating;

- Operating with manuel mechanism from front of panelboard - Operating from main shaft of disconnector

Working with manual drive mechanism

- This is used for operating from front of panelboard. - There can be coil (bobin) for electromagnetic lock.Coil voltages can be 24VDC,48VDC,110VDC,

220VDC,220VAC . - Auxilary switches can be used for signal of disconnector positions. Auxilary switches 2NO+2NC or

4NO+4NC. Back side Front side
