Entellisys Low-voltage Switchgear  

 

Chapter 5.  Installing and Removing Circuit Breakers

Mounting for special 2500-ampere fuse on EGF-16 breaker 

 
 
 

5-8  Installing and Removing Fuse 
Rollout Elements (FRE)

-

30-38-inch 

Wide Compartments

 

The FRE is racked into and out of its compartment just like a 

breaker.  However, the fuse and breaker compartments each 

are equipped with keylocks to prevent racking the FRE when 

its associated breaker is closed.  The FRE also utilizes a 

rejection pin scheme  similar to that used on EGS-32/40/50 

breakers, to prevent installation of an incorrect FRE. 

 

All FRE models feature a hinged, perforated steel screen 

panel in front of the fuses as shown in Fig. 5-17.  This panel 

can be opened to allow access to the fuses, Fig. 5-18, only 

when the FRE is in the WITHDRAWN position.  In all other 

positions, an interference plate attached to the right side of 

the panel prevents it from being opened.  Operation of the 

breaker compartment keylock is the same for all models.  

With the breaker open, the key can be removed; this extends 

the lock bolt, thereby maintaining the breaker in a trip-free 

state while in the CONNECT position Fig. 5-20.  The breaker 

can be racked at will regardless of the keylock position.

fuses 

 

The FRE compartment is KEY INTERLOCKED with the 

associated breaker.  The FRE is locked in the connect position 

until a key is inserted in the FRE key interlock, Fig. 5-19, at 

this time the FRE can be racked out.
