Caseta Tip Cbe - ABB HD4/ESB Series Installation And Service Instructions Manual

Intrerupatorul este prevazut cu contacte tulipa izolate. Intre-
rupatorul debrosabil sunt prevazute cu blocaje speciale, pe tra-
versa frontala, care permit agatarea in articulatiilor corespunza-
toare in caseta. Blocajele pot fi activate doar
cu manileva cu caruciorul asezat complet pe traversa.
Manivela de brosare/debrosare trebuie introdusa complet. Un
blojat previne avansarea caruciorului in caseta (de exemplu cand
separatorul de punere la pamant este inchis). Daca caruciorul
este in pozitie intermediara blocajul previne inchiderea intre-
rupatorului (mecanic sau electric).
La cerere, poate fi prevazut un magnet de blocare care,
cand este nealimentat, impiedica actionarea caruciorului.

5.5. Caseta tip CBE

Pentru informatii referitoare la caseta CBE va rugam sa
consultati documentatia referitoare la aceasta.
The circuit-breaker is completed with the tulip isolating con-
tacts. The withdrawable circuit-breaker is fitted with special
locks, on the front crosspiece, which allow hooking into the
corresponding joints in the enclosure or fixed part. The locks
can only be activated by the handles with the truck resting
completely on the crosspiece.
The activating lever (connection/isolation) must be fully in-
serted. A lock prevents the truck from advancing into the
enclosure or fixed part (for example when the earthing switch
is closed). With the truck in the middle position between
isolated and connected, the lock prevents closure of the circuit-
breaker (both mechanical and electrical).
On request, a locking magnet can be mounted on the truck
which, when de-energised, prevents truck operation.
