Drawout Breaker Interchangeability
I n general, drawout breakers of the same type and rating
are i nterchangeable in their equi pment compartments ;
drawout breakers of different frame sizes are not i nter­
changeable. To prevent inserting the wrong type breaker
i nto a drawout compartment, suitable " rejection hardware"
is aff ixed to each breaker and its compartment. Figure 7
shows a typical rejection bracket which aligns with a rejec­
tion pin in the drawout rail (Fig. 8) . When the wrong type
breaker is inserted into a compartment the bracket and pin
prevent the breaker from seating itself i nto the d rawout
rai ls.
There is one exception to the above . Breakers of the
same frame size having different short circuit ratings may
be interchanged in one direction only :
a. An AKR-30H can be inserted into an AK R-30 compart­
ment.
b. An AK R-50H can be inserted into an AKR-50 co mpart­
ment.
c. An AKR-50H-1 can be inserted into an AKR-50 and
AKR-50H compartment.
d. An AKRT-50H can be inserted i nto an AK RT-50 co m­
partment.
The rejection hardware prevents the converse of a.
thru d. above.
A detailed description of the rejection pin and bracket
co mbinations used is given in Installation manual , G E l
