Our direct replacement upgrade solutions feature new circuit breakers designed to fit into the existing cubicle with little-to-no modification to the switchgear cell. A direct replacement upgrade solution reduces downtime since there is minimal (if any) outage on the equipment bus.
Low-voltage direct replacement circuit breakers
- This solution features Masterpact™ NW/NT circuit breakers with connectivity capabilities
- A standard Masterpact cradle is installed into an adapter cradle to form one assembly, which is then installed into the switchgear cubicle
- This cradle-in-cradle assembly locks into place and remains in the switchgear cell after the initial installation
- The new Masterpact circuit breaker with state of the art Mircologic™ trip units 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
Medium-voltage direct replacement circuit breakers
- This solution features Magnum™ circuit breakers with connectivity capabilities
- Designed to fit into an existing switchgear cell without modification
- Magnum™ circuit breakers will correctly interface with the existing compartment cell and maintain safety interlocks built-in the original equipment design
