Retrofill
The existing switchgear cell and bus are modified to
accept the new circuit breaker. This option requires a
longer bus outage (compared to the direct replacement
option), during which time the internal circuit breaker cell
is modified to accept the new circuit breaker.
A Masterpact cradle-in-cradle design is utilized for LV direct
replacement solutions
Direct Replacement
Circuit breakers are designed to fit into the existing
cubicle with little-to-no modification to the switchgear
cell. Reduces downtime since there is minimal (if any)
outage on the equipment bus.

• A MasterpactTM cradle is installed into an adapter cradle, which is
then installed into the switchgear cubicle.
• This cradle-in-cradle assembly locks into place and remains in the
switchgear cell after installation.
• The new Masterpact circuit breaker racks in and out of the adapter
cradle.
• A new door is installed, however cell interlocks, the racking
mechanism and the switchgear structure are not modified.

Did You Know? New switchgear is usually smaller than the equipment it is designed to
replace. The existing conduit may need to be moved and cabling replaced or spliced. Both
are expensive and time consuming tasks, often costing more in labor and material than the
cost of the new equipment .

breaker and cell into an existing line-up. Necessary modifications
are made to the existing cell and include:
A retrofill solution is often used in lieu of the direct
replacement option for larger devices, such as main
breakers and tie breakers.
Designs are available for any
manufacturer’s switchgear and include:
• Air-magnetic to vacuum or SF6
• Air-blast to vacuum or SF6
• OCB switchgear to vacuum or SF6 switchgear
• Convert stationary circuit breaker to draw-out,
or obsolete air circuit breaker to vacuum or SF6
