Entellisys Low Voltage Switchgear
Chapter 3. Description
Fuses for the charge, close, and trip circuits of electrically
operated breakers are mounted in the upper left corner of the
breaker compartment behind the door. Fuses for the set and
reset coils of the optional Network Interlock breaker
accessory are mounted in the upper right corner of the
compartment.
Primary disconnect shutters are available as options to
provide protection against contact with the energized
stationary primary disconnects when the breaker is removed
from its compartment. Shutters are supplied as standard
components in the source (main, generator) and tie breaker
compartments of multi-source lineups. The shutters are
constructed from glass-reinforced polyester insulating
material.
NOTE: If a fuse rollout (FRE) carriage is used with an
EGF-32/40/50 circuit breaker whose compartment is
equipped with shutters, the FRE compartment will also be
equipped with shutters.
NOTE: Si on utilise un chariot porte-fusibles à roulettes
avec un disjoncteur EGS-32/40/50 dont les compartiments
sont munis de volets, le compartiment du porte-fusible à
roulettes sera aussimuni de volets.
The combination of the stationary and movable portions of
the shutters prevent frontal access to the primary disconnect
line and load power stabs.
