interface.
b
The electrical auxiliaries are combined with
iC60 circuit breakers, iID residual current circuit
breakers, remote tripping switch disconnector
iSW-NA , RCA remote controls and ARA
automatic reclosers; they enable tripping or
remote indication of their position (open/closed/
tripped) upon a fault.
b
They are fastened by clips (without tools) to
the left side of the breaker.
b
The iOF/SD+OF auxiliary is a 2-in-1 product:
via a mechanical selector switch, it provides two
contacts, OF+SD or OF+OF.
b
The iOF+SD24 auxiliary can report open/
closed (OF) status information and intentional or
fault tripping of the associated device (SD) to
the Acti 9 Smartlink or a programmable logic
controller via the TI24 interface (24 V DC).
