Chapter 3. Description
3-5 Breaker Compartment
Closed-door drawout circuit breaker compartments,
Fig.
3-
4, are standard construction with all Entellisys switchgear
equipment. The circuit breaker compartment doors
remain closed and latched while the breaker is racked out
from the connected position, through test, to the
disconnected position.
Breaker compartment doors do not have any ventilation
slots, thus protecting operators from hot ionized gases
that may be vented by the breaker during circuit
interruption.
Additionally, the breaker compartment, Fig. 3-5, is enclosed
by grounded steel barriers on the top, sides, bottom, and
front. In the back, a flame-retardant, track resistant, glass-
filled polyester base minimizes the possibility of fault
communication between compartments or to the bus.
