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.
