As switchgear reaches the end of its intended useful
life, a viable, cost-effective strategy is to modernize the
existing equipment with the latest state of the art circuit
breakers. Modernizing existing equipment is a
cost-effective solution to upgrade the capabilities
of your electrical system with minimal downtime.
Benefits of Modernizing
Existing Switchgear
• Reduced costs for switchgear upgrades
»» New circuit breakers are installed in
existing switchgear
»» Original footprint is left intact, saving time
and money
»» Upgrades can be performed on an
incremental basis
• Less downtime for installation
»» Downtime is minimized when compared
with the demolition and replacement of
existing equipment
For existing switchgear
line-ups, we offer new customengineered direct replacement
circuit breakers which are
designed to fit into the existing
switchgear cell with minimal
modification and down-time.
A direct replacement solution
utilizes the upgraded technology
of our Masterpact™ NT/NW
insulated case circuit breaker for
low-voltage systems or the
Magnum™ circuit breaker
for medium voltage
systems.
• Enhanced equipment reliability
»» New circuit breakers undergo complete factory testing
and are backed by our standard equipment warranty
• Reduced maintenance and operating costs
»» New, easy-to-maintain operating mechanism
»» Reduced need for difficult to obtain spare parts
Designs available for ANY brand.
