Note
*1 Rated current of IEC standard
*2 Trip relay is divided into 50Hz and 60Hz. Please be careful when you order it.
*3 The generator protection relay is only available in OCR-III.
*4 For mainbody, only horizontal type is available. For cradle, vertical type is optional. In case of vertical type use of the horizontal type, the user needs to apply the vertical adapter, The vertical type is standard for 4000/500AF.
*5 For 4000/5000AF, height is 455mm
Charging method
Manual charging type
The closing coil is charged by manual charging handle. For closing, first charge the spring by using the charging handle, and then press the close button(I, ON) for closing, the open button(O, OFF) for opening
|
Motor charging type
The closing spring is charged by a motor ON charging method or OFF charging method is available selectively.
-OFF charging method : When the breaker is opened, the closing spring is charged automatically. It can change to ON charging method by removing b(A×b) contact like beside circuit diagram
-ON charging method : The closing spring is charged automatically when the breaker is closed.It can change to OFF charging method by using b(A×b) contact. There is a contact to indicate the charging completion(TS+, TS-). Since the contact signal of charging completion switch is connected to the external terminal, It is easy to construct a circuit(ex.Automatic closing circuit) by using that contact

5:OCR Alarm contact
OCR alarm contact is fundamentally installed in only ACB with trip relay.
When the ACB is tripped by the OCR operation, electrical signal flows through the OCR alarm contact for remote supervisory(INO).
